Domain name explained

The domain name is a unique identifier that is utilized for accessing websites. Thanks to the Domain Name System (DNS) – a hierarchical naming system that translates domain names into IP addresses, users can connect to websites using domain names. Compared to IP addresses, domain names are very easy to remember for regular users. 

The structure of a domain name, starting from left to right, is the following: 

• Subdomain: It is located on the left side of a secondary domain and serves as an extension to the primary domain. A subdomain, such as blog.site.com, represents a separate website section. It should be noted that not every domain has a subdomain.
• Second-Level Domain: It is positioned in the middle of a domain name and is usually the most memorable part of the domain structure. People commonly use their personal or business names.
• Top-Level Domain (TLD): It is the extension at the very end of the domain name, such as .com or .net.

The complete version of a domain name, also known as the Fully Qualified Domain Name (FQDN), also includes the hostname.

Now that you know more about domain names and the position of the TLD (Top-Level Domain), let’s explain a little bit more about what it actually is.

What does TLD stand for?

The short acronym TLD stands for Top-Level Domain and represents the last part of the domain name, located after the last dot. Also known as domain extensions, TLDs can help to recognize some aspects of a website, such as its purpose or geographical area.

In the Domain Name System (DNS) hierarchy, the TLD (Top-Level Domain) defines the first stop after the Root zone. Additionally, it has an extremely vital role in the DNS lookup process (DNS resolution). When a user types a domain name into their browser, like example.net, the Recursive DNS server searches the corresponding IP address by communicating with many servers, including the TLD server. In this case, the TLD is .net, so the Recursive DNS server will contact the TLD server responsible for all domains with the extension .net. Then the search continues until the Recursive DNS server gets the requested IP address from the Authoritative DNS server of example.net.

The Evolution of TLDs

In the early days of the Internet, there were only several TLDs, and securing a .com domain was the ultimate goal for businesses looking to establish an online presence. However, as the Internet expanded, the demand for domain names grew as well. That led to the introduction of a more diverse range of TLDs.

The introduction of new gTLDs (generic top-level domains) has been a game-changer. These gTLDs are more specific and offer a wider collection of choices for domain names. Some popular gTLDs include .app, .blog, .guru, .tech, and .io, to name just a few. These new gTLDs have opened up a world of creative possibilities for domain names and allow businesses and individuals to craft web addresses that are more relevant to their specific niche.

Types of TLDs

There are several main types of TLD (Top-Level Domain).

Generic Top-level Domains (gTLD)

They are the most popular TLDs, and they can serve so many different purposes. Here are some of the most popular generic TLDs:

• .com – At present days, it’s the most widely used TLD. Yet, originally it was used for commercial sites. 
• .net – At first, it was utilized by businesses working with networking technology. Currently, all sorts of organizations and companies benefit from it.
• .org – It comes from “organization,” and that is why it is very suitable for many nonprofit associations.
• .tech – A very suitable and preferred choice for tech companies.
• .biz – A great extension of all kinds of businesses.

Country Code Top-level Domains (ccTLD)

The ccTLDs illustrate different countries and geographical areas. They are usually two-letter codes specified by ISO 3166-1 alpha 2. An interesting fact is that there are more than 300 ccTLDs in the IANA’s list. The reason for that is simple ccTLDs can also illustrate sovereign states and dependent territories. Here are several examples of popular ccTLDs:

• .us – United States
• .ca – Canada
• .de – Germany
• .fr – France
• .cn – China
• .es – Spain

Sponsored Top-level Domains (sTLD)

Sponsored Top-Level Domains, according to the name, are proposed and supervised by private organizations. Usually, these entities are businesses, government agencies, and different organized groups.

The Sponsored Top-Level Domains (sTLD) list only contains a short number of alternatives. Back in the day, such types of TLDs were only .edu, .gov, and .mil. Yet, in recent years have been created new Sponsored Top-Level Domains and their number has increased. 

Here are some of the most popular sTLDs:

• .gov – for United States governmental agencies
• .edu – for higher educational organizations
• .mil – for usage by the US military
• .museum – for museum institutions
• .travel – for travel industry companies

Infrastructure Top-Level Domain (ARPA)

The Infrastructure Top-Level Domain is a special category that actually includes just one single TLD, which is the Address and Routing Parameter Area (ARPA). In addition, IANA directly manages the domain extension .arpa for the Internet Engineering Task Force (IETF) under the guidance of the Internet Architecture Board (IAB). It is utilized only for technical infrastructure purposes.

Test Top-Level Domains (tTLD)

The Test Top-Level Domains, also known as tTLD, are extensions reserved for local testing and documentation objectives only. Therefore, they can not be established in the global Domain Name System (DNS).

Here are the four tTLDs:

• .test – reserved for testing various scenarios or software
• .localhost – used for testing local networks.

What is Localhost (IP 127.0.0.1)?

• .example – dedicated for placeholders and documentation objectives
• .invalid – displays invalid domain names

Who’s accountable for managing TLDs?

ICANN is responsible for managing the TLDs. The short acronym stands for Internet Corporation for Assigned Names and Numbers, which is actually a non-profit organization. That is possible thanks to a division of ICANN known as IANA (Internet Assigned Numbers Authority).

In addition, ICANN/IANA delegates some of the responsibilities for certain Top-Level Domains to other organizations.

How to choose the right TLD for you?

Choosing a TLD could sometimes be overwhelming. So here are a little bit more details and tips that will help you make your decision more effortlessly.

• Choose a TLD that corresponds to your business characteristics.
• Keep it short. That way, you make it clear and concise, and your visitors don’t get confused when writing your domain name into their browsers.
• Check availability. The combination of your SLD and your chosen TLD could be already taken.
• Target your market. Choose a specific ccTLD, in case you want to focus on a precise county.
• Exact match with your brand. Make sure to register a domain name that is not misspelled. That would confuse your visitors.
• Popular TLDs, like .com, .org, net, and .info, are usually considered more trustworthy by regular users. 
• Consider new gTLDs. By selecting a newer TLD, you can distinguish your business from opponents. Additionally, some of them help you create amazing domain names. For example, there are industry TLDs like .film, .press, .digital, and more. 

Why TLDs Matter?

When it comes to establishing a web presence, your choice of a Top-Level Domain (TLD) isn’t just a matter of aesthetics. It’s a strategic decision that can significantly impact your online identity. 

Top Level Domains play a crucial role in defining the purpose, scope, and geographic relevance of your website. They help your visitors understand the nature of your online presence. For instance, a .com TLD traditionally signifies a commercial website, while .org often indicates a nonprofit organization.

We’ll also discuss how TLDs influence search engine optimization (SEO) and user trust. Understanding the importance of Top Level Domains can help you make an informed choice that aligns with your brand, target audience, and marketing goals. 

The Impact of TLDs on SEO

The choice of TLD can impact your website’s search engine optimization (SEO) efforts. While it’s true that Google’s algorithms treat all TLDs equally, user behavior can differ depending on the domain extension. Here’s how your Top Level Domain can influence SEO:

• Credibility and Trust: Traditional TLDs like .com, .org, and .net are often associated with credibility and trust. Users tend to trust websites with these domain extensions more, which can indirectly affect your SEO.
• Keyword Relevance: If you include relevant keywords in your domain name, they can contribute to your SEO efforts. For instance, if you run a plumbing business, a domain like “www.yourplumbingexperts.com” can help your website rank higher for plumbing-related keywords.
• Geotargeting: Country code TLDs (ccTLDs) can help your website rank well in local searches. If you’re a local business, using a ccTLD can be beneficial for your SEO in your target region.
• Niche Relevance: Using a domain extension that is relevant to your niche can signal to both users and search engines that your website is focused on a specific topic, potentially improving your rankings for related keywords.

It’s important to mention that while the choice of TLD can have an impact on SEO indirectly, it is just one of many factors. High-quality content, backlinks, website speed, and mobile-friendliness still play more critical roles in your website’s ranking on search engine results pages (SERPs).

The Importance of TLD in Branding

Top-Level Domains (TLDs) play a crucial role in branding by shaping the first impression of a website and influencing user perception. Traditional TLDs like .com, .org, and .gov are widely recognized and associated with established, reputable organizations. Users often perceive sites with these TLDs as more credible, which can reinforce brand identity. For nonprofits, the .org TLD is often preferred because it signals authenticity and a mission-driven focus, while government and educational institutions use .gov and .edu, respectively, to communicate authority and reliability. 

Newer, industry-specific TLDs like .tech, .store, and .design allow businesses to communicate their niche directly through their domain, making them instantly recognizable to targeted audiences. Selecting the right TLD is essential as it communicates brand credibility, relevance, and industry focus, which can enhance customer trust and reinforce the brand message.

Future Trends in TLDs: What’s on the Horizon?

The future of Top-Level Domains (TLDs) points toward increased diversity, personalization, and regional relevance. With thousands of TLD options now available, businesses and individuals are looking beyond traditional options like .com to more unique and memorable TLDs that better reflect their brand identity. We can expect a continued rise in specialized TLDs that cater to niches like .tech, .shop, and .media, enabling brands to create highly specific web addresses that stand out in search results and user memory while also making their purpose immediately clear to users.

Geographic and regional TLDs are also expected to see more growth. TLDs like .nyc, .paris, and .tokyo are gaining popularity as businesses aim to establish local relevance. These TLDs support geotargeting in SEO strategies and appeal to users who seek local services, thus building brand trust and visibility within specific regions.

Another significant trend is the focus on cybersecurity. New TLDs with enhanced security protocols, such as .bank and .insurance, are on the rise, providing users with added assurance. This shift reflects a broader trend of using TLDs to express trustworthiness and enhance user confidence in online interactions.

Finally, the rise of new technologies, including blockchain, has introduced decentralized domains. These TLDs operate outside traditional ICANN regulations, allowing users more control over their digital presence without intermediaries. While still experimental, this trend hints at a future where decentralized domains could play a larger role as blockchain technology advances.

Conclusion

The Top-Level Domain (TLD) is very important and provides details about your business purpose or location. Additionally, it helps you reach the desired market. That is why it is crucial to confuse your audience. There are lots of different types of TLDs. So, make sure to choose one that better suits your needs.

To be more precise, the domain name resolution is a translation process between the domain name that people use while writing in their browsers and the site’s IP addresses. You need the IP address of a site to know where it is located and load it.

A website could have both IPv4 and IPv6 addresses, and the DNS resolution of a domain name will ask for both of them. The IPv4 address will come in the form of a DNS A record, and the IPv6 will come in a DNS AAAA record.

Let’s get into the details, and see how it works, shall we?

Domain name resolution – Why is it important?

In the world of the Internet, the addresses don’t contain streets and cities. They have numbers and symbols. There are two types of addresses: IPv4 and IPv6. In order to enter a particular website, the user needs to get its IP. Instead of remembering all of the IPs of every website, we simply need to remember the domain name. The domain name is usually not hard to remember, and this makes it easier. When the user types the name of the website, the process of the domain name resolution starts.

So let’s proceed and explain the whole process of DNS resolution.

DNS resolution process

The browser of a user needs to get the IP and sends queries to the name servers. This process involves domain name resolvers. The first answer that your browser will get is the root server, then the TLD (top-level domain). The servers with the TLD of the website you want to visit (com, net, or another) will refer your queries to the next step in searching authoritative servers that know the exact IP address of the domain name. Then the domain name will be resolved.

Let’s breakdown the DNS resolution step-by-step: 

1. A user is typing a domain name like cloudns.net into their browser. The user needs an A or AAAA DNS record to resolve the domain name.
2. If your device’s cache has the IP address of cloudns.net, the domain name resolution will finish here, and the user will be able to open the website. But, if it does not, there will be more steps. The devices keep DNS records for visited sites, depending on the TTL (Time to Live) values of those DNS records. After the time they indicate, they will be deleted, and a new query needs to be performed.
3. If your computer doesn’t have the needed IP address, it will search for the answer by performing a DNS resolution query. The next destination on the way will be the recursive DNS servers of the internet services provider. They also keep a cache with DNS records of domain names that users have accessed. If the desired site’s DNS records are still there, the user will get an answer to its query and access the site. If not, there will be a series of interactive DNS queries to find the answer.
4. If the domain name resolution didn’t finish with the previous step, the recursive nameserver would search for the answer. The next step will be to ask the Root server, which is indicated with a “.” sign after the TLD (top-level domain). The Root server does not have an answer about the exact domain name, but it will provide one for the part it is responsible for – it will indicate all the nameservers for the TLD that we asked for. In our case, it will show the nameservers of .net.
5. The TLD DNS servers will have the answer of which exactly are the authoritative nameservers for the domain you are searching. The TLD servers of .net will have that information for all of the domain names that finish with .net. They will return that answer so the query can continue.
6. Now that we know where the authoritative nameserver of the domain name we want is, we can ask and get the A and AAAA records to understand the site’s IP address.
7. The Authoritative nameservers of the domain name will provide the DNS records, the DNS resolution will be made. The recursive nameserver of our ISP and our device will both save the DNS records that we obtained based on their TTL values. That way, if we soon want to visit the site again, we will save time and access the site faster.
8. Visit the site. Now with the DNS record already obtained, the user can access the site.

Do we need to care about it?

The answer is yes! For humans, the DNS resolution process is essential. And if something goes wrong, the use of the Internet by regular users would be extremely difficult. 

So we should be concerned about DNS resolution for two reasons:

1. The first one is the importance of the speed. When a user accesses your website, the DNS resolution is the first thing that happens. If your page takes too long to load and access, the user will probably leave. That’s why this process needs to be performed fast.
2. The second one is the availability. The nameserver in charge of handling your domain name needs to be trustworthy. A backup DNS service is a great technique to guarantee that your domain is always reachable by your customers.

What to do if DNS resolution is not working?

1. Check your internet connection. Many times when the domain name resolution fails, the main reason is that you are not connected to the Internet. Check your connectivity and restart your router.

2. Verify the problem is DNS-related. Before diving into DNS-specific solutions, confirm that the issue isn’t related to general connectivity. Try accessing the site with its IP address instead of its domain name. If this works, the problem likely lies with DNS resolution.

3. Obtain DNS server address automatically. Go to the network adapter and open the properties. Then search for the Internet Protocol Version 4 (TCP/IPv4) and open its properties. From there, you can click on Obtain DNS server address automatically. This will allow your computer to receive the DNS settings from the DHCP server.

4. Release and then renew the DHCP IP address. There could be an IP address conflict because of the DHCP server. What you can do as a user is to give up the IP address lease. You can do that with a command from the Command Prompt:

ipconfig /release

After that, you can renew your IP address with the following:

ipconfig /renew

Now your connectivity should be restored.

5. Flush the DNS cache of your device. You can do that by accessing the Command Prompt (as an administrator) and performing the following command:

• On Windows, open Command Prompt and type: ipconfig /flushdns
• On macOS, open Terminal and type: sudo killall -HUP mDNSResponder
• On Linux, the command varies by distribution, but a common one is: sudo systemctl restart nscd

If you had a previous IP address of a domain that is no longer available, now you have deleted it. The device performs a DNS resolution again, and it should get the new IP address.

6. Disable any VPNs or proxies. VPNs and proxies can redirect your network traffic through different servers, which may cause DNS resolution issues. Try disabling them to see if that resolves the issue.

7. Check your hosts file. The hosts file on your computer can override DNS and manually map domain names to IP addresses. Ensure there are no incorrect entries that could be causing conflicts.

• On Windows, this file is located at C:\Windows\System32\drivers\etc\hosts
• On macOS and Linux, it’s at /etc/hosts

8. Update your DNS records. If you’re managing a domain and have recently changed DNS records, it might just be a matter of waiting. DNS propagation can take up to 48 hours.

9. The last resort is to contact your ISP and tell them the problem. There is a chance that it is related to its equipment or software, and it can fix it. Or maybe it is blocking some websites on purpose. You can at least try to find an answer from it.

DNS Monitoring: Keeping Resolution on Track

DNS resolution is a silent yet critical driver of the digital world, translating domain names into IP addresses. DNS monitoring services amplify this process’s reliability by offering continuous oversight. These services rapidly identify and help rectify resolution delays or failures, ensuring users can always reach their online destinations.

DNS monitoring checks are essential in validating the seamless operation of DNS resolution, crucial for uninterrupted internet navigation. By querying specific hostnames against expected responses, these checks can swiftly flag a DNS resolution process as operational (UP) or problematic (DOWN).

For example, monitoring might run a command like:

If the response matches the expected IP, the DNS is considered healthy. This proactive measure ensures DNS performance remains robust, which is vital for network reliability and the overall user experience.

In the event of discrepancies, debugging tools, including Traceroute, assist in tracing the issue to its source, allowing for quick resolution. Thus, integrating DNS monitoring checks is a strategic move to bolster network stability and maintain consistent service delivery.

Why do we need recursive servers?

Theoretically, authoritative nameservers are enough to keep the DNS resolution process running. You can think that the only kind of DNS servers we need is authoritative, but imagine how much load they will need to take if all the complete queries get to them.

For decreasing the load and increasing the speed, there are recursive servers (DNS resolvers) that keep the DNS records with the information needed to access a particular website for a defined period of time. This time is called TTL (time to live), and the process is named DNS cache. There are such recursive servers in the internet service providers that keep the information for many websites for the period of time defined by the TTL.

To make it easier to imagine, it generally functions as a name server, acting as a go-between the customer and the authoritative DNS server. However, without it, you won’t be able to access any website that you want to reach on.

Why DNS Resolution Times Matter and How to Improve Them

DNS resolution times are a key factor in overall website performance, as they determine how quickly a user can begin accessing a webpage. If this process takes too long, it can significantly delay page load time, creating a poor user experience. Delays have a negative impact on e-commerce and business sites, where faster loading speeds directly affect sales and user engagement.

Several factors influence DNS resolution speed are the following:

• Server Proximity: The closer the authoritative DNS server is to the user, the faster the response. Many DNS providers use Anycast routing, which directs queries to the nearest server, reducing latency and speeding up resolution times.
• Caching Efficiency: When DNS records are cached effectively, repeat queries can be answered instantly from the cache, avoiding the need for a full DNS lookup. Time to Live (TTL) values determine caching duration – longer TTLs reduce query frequency for stable sites, while shorter TTLs allow for more frequent updates.
• DNS Provider Choice: A reliable, high-performance DNS provider often has better infrastructure and caching policies, as well as multiple server locations worldwide, which can reduce resolution time. Providers typically offer faster, more secure DNS resolution than ISP default options.

How DNS Resolution Works with IPv4 and IPv6 Addresses

When domain resolution occurs, it can return either IPv4 or IPv6 addresses or both, depending on the server’s configuration and the client’s capability to use either protocol. This flexibility ensures that DNS can adapt to the gradual transition from IPv4 to IPv6, supporting both legacy systems and modern networks.

The two address types serve distinct purposes:

• IPv4 (Internet Protocol version 4): IPv4 is the older protocol that uses 32-bit addresses, resulting in about 4.3 billion unique IPs. DNS A records are responsible for mapping domain names to their corresponding IPv4 addresses. However, with the explosive growth of internet-connected devices, IPv4 addresses are in short supply, which is where IPv6 steps in.
• IPv6 (Internet Protocol version 6): IPv6 was developed to provide a vast address space, using 128-bit addresses that allow for 340 undecillion unique IPs. This address space is critical for the future of the internet, as more devices connect daily. DNS AAAA records are responsible for returning IPv6 addresses for a domain. Additionally, the newer version of IP offers benefits beyond capacity, including better routing efficiency and improved security features.

Conclusion

DNS is a very useful system that saves a lot of time and makes our lives easier. After this article, you will know better what happens when you open a web page, how exactly the DNS resolution works, and what it means a domain name resolution.

The post What is Domain Name Resolution? appeared first on ClouDNS Blog.

DNS outage (DNS downtime) – what does it mean? 

The DNS outage (a.k.a. DNS downtime or DNS failure) is a period of time when the domain name can’t be resolved to its IP address. The clients will send a DNS query for a domain name, but the DNS recursive will either answer with the old IP address from its cache, which will not respond, or it will try to query the DNS authoritative name server of the domain name won’t get an answer. 

What causes DNS outages? 

DDoS attacks

DDoS or a denial of service attack, is a type of cyber-attack that involves multiple devices that work together, targeting a victim’s computer, with a large amount of traffic intending to make it unable to answer any more queries. To prevent any problems that a DDoS attack can cause, you will need a load balancing that can share the traffic between your servers, even if it is very strong. And also, you will need DDoS-protected servers. 

Maintainance of the authoritative name server

If you are using only one authoritative name server, whatever happens to it, can affect your DNS. If it needs updates and reboot, the time that it takes, the server won’t be able to respond to DNS queries. Updates and maintenance are needed, so you better have a Secondary DNS that can answer the queries meanwhile. 

A problem in the data center, where the authoritative name server is

The cloud equipment does not magically hover over the Earth. Instead, it resides in multiple data centers. These places can have problems like long-lasting electricity outages, natural disasters affecting the area, fire, or other problems. If you are using a cloud service, these issues are out of your hands, but you can use multiple servers in multiple data centers. If one is down, still, there will be more to answer the queries. 

Bad configuration

Errors in DNS configuration can cause DNS downtime. It can be a human mistake, like badly addressing caused by misspelling the IP address or domain name, script error, wrong firewall configuration, etc. 

If it is a misspelled problem, you can try to query the domain name and the IP address to see which does respond and which does not. 

If it is the firewall, you can check the ports if they were allowed. 

DNS propagation delay

When you add or remove DNS records (like A or AAAA records), the changes are not always instant. You are editing the zone file inside the Primary DNS server, and you can propagate to your Secondary DNS servers, but there are many DNS recursive servers that you don’t control. They can keep your old IP address and provide it to clients, even after you published a new one. 

What you can do about the DNS propagation is to push the zone transfer to your Secondary servers and to keep lower TTL values for your DNS records. 

It is not technically a DNS outage because it will affect only those with the older cached IP address of the domain name, but it was worth mentioning it.

How to avoid DNS downtime (outage)

The best way to avoid DNS outages is to have a robust DNS network that provides redundancy and can withstand strong traffic. The more servers you have, the better you are going to be prepared. Additional features might also facilitate the DNS administration and automate the process of handling problems. 

Use Secondary DNS services

A secondary DNS service provides you with the opportunity to use multiple Secondary DNS servers, which can be set as Secondary authoritative nameservers. They will have a copy of the zone file with the DNS records. They can answer queries for your domain, just like the Primary one. The big advantage is that they will keep answering even if the Primary is experience downtime. Having Secondary DNS is your DNS backup solution. 

You can learn more about it in this article, “What is backup DNS?”, and you can try our Secondary DNS plans with a 30-day free trial. 

Use DNS load balancing

DNS load balancing is also another nifty way to lower the chance of DNS outages. It is a mechanism for administrating the DNS traffic between the DNS server, based on criteria like the number of active connections, specific algorithm, time of connection, etc. 

It will reduce the stress on a particular DNS server and spread it between the network. 

It can help in case of a DDoS attack but also in a natural spike in traffic caused by increased clients’ queries. It can help you during a promotional period when you are experiencing higher traffic.

Be prepared with DNS Failover

DNS Failover is a trigger that will activate in case of a nameserver’s failure. It can automatically redirect the traffic without any human interaction, based on the information it gets from DNS monitors like ICMP ping, UDP requests, HTTP checks, etc. It is an easy way to keep your clients’ happy and provide DNS resolution, even if some of your DNS servers are experiencing some problems. We offer DNS Failover service with all of our paid plans.

Also, we recommend you to check our Brand new Monitoring service!

How to diagnose DNS outages?

When facing a DNS outage, quick diagnosis is essential to restore functionality. Follow these steps to pinpoint the problem:

• Ping the Domain

Use ping to check if the domain resolves and the server responds.

ping example.com

If it doesn’t resolve, it’s likely a DNS issue.

• Test DNS Resolution with nslookup

Verify if DNS is working by querying your DNS server with nslookup.

nslookup example.com

If it returns an IP address, DNS is working for that domain. But if it fails, the DNS server may be down or misconfigured.

• Run dig for detailed queries

Use dig for detailed DNS resolution data, including specific DNS record types.

dig example.com

Add +trace to follow the query path through name servers and find where it fails.

• Test with Alternate DNS Servers

Query public DNS servers (like Google’s 8.8.8.8) to rule out provider-specific issues.

nslookup example.com 8.8.8.8

If the domain resolves with a different DNS server, it suggests the problem is with your original DNS provider.

• Check DNS Propagation Delays

If you’ve recently made DNS changes (such as updating A or MX records), delays in DNS propagation could be the culprit. Use online tools like ClouDNS Free DNS tool to check whether your DNS records have propagated across global DNS servers.

• Check for DDoS attacks or high traffic loads

DNS outages can be caused by Distributed Denial of Service (DDoS) attacks or heavy traffic loads. Tools like TCPdump can help capture and analyze DNS traffic to detect abnormal patterns, such as a flood of queries or unusual IP activity.

Example:

sudo tcpdump -i eth0 port 53

This command captures DNS traffic, allowing you to inspect for signs of an attack. For real-time detection, combine TCPdump with network monitoring tools and DDoS mitigation services.

Troubleshooting 

What can you do when your domain is not reachable? 

As DNS administrator of the domain name, you can: 

• Suppose you have recently finished a DNS delegation. You might need to way up to 24 hours, so the changes are well propagated. 
• Check if you have paid for your domain name. If you have forgotten to pay your domain name, it won’t answer queries anymore when it expires. Set reminders for domain renovation and don’t miss the time. 
• Use the ping command to ping the DNS server from different locations to see if it is responding to any DNS requests. It is possible that you haven’t set up your nameservers correctly, and they are working but not answering queries for the domain name. 
• Try to reach the DNS server by using its IP address. If you can reach it, there might be a badly configured A or AAAA record that does not link well the domain name and its IP address. 
• Check your DNS monitor and see how the traffic is going. If you can’t see the monitor’s log, check if there were any unusual activities before the server stopped working. For example, it could have been a DDoS attack. If it is still happening, you can redirect the traffic and stop it. 

As a client who can’t reach a site: 

• You can have problems with the DNS cache of your device. You can flush the DNS of your device and your browser. This action will remove the previous DNS records that you have, and your device will search again for the A or AAAA record of the site you want to visit. If you had an older IP address, this could fix it. 
• Maybe your router is the problem. The router has a recursive DNS server that may need to be restarted. Pull its plug, then wait around a minute and connect it again. It should reboot and start working well again. 

Monitor your DNS server

Monitor your DNS for any strange pattern in traffic. There are different automatic monitors that you can set to see the traffic behavior. If something strange happens, you can see in almost real-time any changes and use the information to take action. 

You can monitor the DNS from different locations. That way, you can see if the problem is very local, is it regional, continental, or global. It will be easy to spot the problem.
DNS monitoring works best in combination with DNS Failover. You can set the monitor with the parameters that you prefer, and it will notify you and show you the data. But when you also have DNS Failover, you can connect this data and trigger automatic even in case of a down server. It can deactivate DNS records and replace them with working. It can also react in case the server gets up and add it to the list again. 

ClouDNS offers DNS Failover service for all of its paid customers. You can set it up and activate it for your domain fast and easily.

What are the consequences of a DNS outage?

If a DNS outage occurs, it could have a negative impact on your entire organization and community of customers. When DNS (Domain Name System) is down, websites, applications, and online services related to the domain name, such as emails, won’t function correctly. Unfortunately, that has the potential to damage operations, revenue, and brand reputation. In addition, you should act fast and quickly get it up and running again to regain all the temporarily lost functionality.

Yet, let’s assume the functionality of the DNS operations was seriously interrupted for a prolonged period of time. In that case, a DNS outage can potentially cause devastating consequences to the companies with an online presence. Here are some of the most common effects during this time: 

• Miss potential visitors
• Lose potential sales
• Have issues with services like email, FTP, VoIP, etc.
• Productivity losses
• Damage to reputation
• Impact on customers and strategic partners
• Diminished competitive advantage

It is crucial to implement all precautionary measures to avoid DNS outage’s negative influence on your business.

The biggest DNS outages in the history

Conclusion

A huge DDoS attack can lead to a DNS outage even if you have excellent infrastructure. But applying all the measurements can lower the time and the frequency of the DNS outages. Be prepared and intelligently manage your DNS traffic to be able to provide excellent service for your clients. Keep your business up!

Understanding Domain Parking

Domain parking is the practice of registering a domain name without attaching it to an active website. Instead, the domain is directed to a basic placeholder page, which may display an “under construction” message, contact details for potential buyers, or advertisements. This approach allows the domain owner to reserve the name for future use, potentially earn revenue through ad clicks, or list the domain for sale while keeping it inactive.

Why and when to use Domain parking?

There are several reasons and scenarios where domain parking might be useful:

• Site under construction

You could have a brilliant idea for a website. You have the whole concept in your mind, but you don’t have enough time to start it now. You can simply buy the domain with the perfect name for your site and park it. It will be waiting for you until you have time to really start it.

• Domain flipping

There are many people who trade domain names. The process is called Domain flipping. They buy many domain names and don’t create websites. They make a portfolio of different domain names and sell them. In this situation, people use the Domain parking to put their contact information for potential buyers.

• Ads

Some services are available that allow users to create an HTML page with various ads. Users who browse the internet can visit the domain name and think it is a complete site, but actually, it is just a shell with many ads. This can provide a static income to the owner of the domain.

How does Domain parking work?

Parking a domain involves several simple steps, which are the following:

1. Registering the domain: It all starts with securing a domain name. Investors often choose domain names based on popular keywords, brandable phrases, or potential future business ideas.
2. Choosing a Domain parking service: There are numerous Domain parking services available. When you park your domain with such a service, they’ll typically provide a default landing page filled with contextual advertisements. 
3. Earning revenue: When visitors click on the advertisements displayed on your parked domain, you earn a share of the revenue generated from those clicks. The type of ads and the amount you earn can vary based on the parking service you choose and the relevance of your domain name to popular search terms.
4. Selling the domain: If your goal is to sell the domain, you can list a price or set up a contact form for potential buyers to make an offer. Many Domain parking services offer brokerage or listing services to facilitate domain sales.

Alternative to the Domain parking

There an alternative to the Domain parking service which are as follow:

• Web Hosting: Investing in web hosting allows for a customized HTML landing page, offering more flexibility in design but with added costs.
• Domain Forwarding: An effective method for businesses with multiple domains, domain forwarding redirects visitors from one domain to an existing webpage, streamlining user experience.

Things to keep in mind:

• Domain renewal: Just because your domain is parked doesn’t mean you can forget about it. Make sure to renew your domain registration to prevent losing it.
• Traffic is key: The success of a parked domain, especially for monetization, largely depends on the amount of organic traffic it receives. Domains that are typo variations of popular sites, or those with popular keywords, generally see more success.
• Choose the right service: Different domain parking services offer varying revenue-sharing models and display different types of ads. It’s essential to research and choose the one that aligns with your goals.
• SEO implications: If you’re considering transitioning a parked domain to a live site, remember that a domain with a long history of being parked might initially face challenges in search engine rankings.

• Passive Income Opportunity: For those with a talent for identifying valuable or popular domain names, domain parking can be a source of passive income. By displaying ads on the parked domain, you can earn revenue from clicks, making it an effortless way to monetize unused domain names.
• Domain Security and Protection: Parking your domain ensures that it’s safely reserved under your name. This prevents others from registering the domain, which can be particularly important if you’re safeguarding a brand name or a potential business venture. It also adds a layer of protection against domain squatters who might try to exploit unregistered domain names.

Conclusion

In conclusion, Domain parking is a practice where domain owners reserve their domain name on the internet, put it on hold or use it for generating ad revenue. This is typically done by individuals or businesses who either want to secure a domain name for future use, are interested in reselling, or aim to monetize on ad revenues from parked domains. While it does have its benefits in terms of cost-saving, revenue generation and domain name security, domain owners need to be mindful of domain renewal and the chosen parking services.

What does ccTLD mean?

The short acronym ccTLD stands for country code Top-Level Domain, and it is a domain extension that represents a specific country or territory. These domain extensions are derived from the ISO 3166-1 alpha-2 country codes, which are internationally recognized codes for identifying countries and territories.

Each ccTLD is associated with a precise country or territory and indicates a website’s geographic location or target audience. For example, .us represents the United States, .de represents Germany, and .ca represents Canada.

Businesses commonly use such extensions to establish a local online presence or target specific regional markets. Using ccTLDs helps organizations to build trust, credibility, and relevance with the target audience by showing a commitment to serving customers in a specific country or region.

History of ccTLD

The origin of country code top-level domains (ccTLDs) dates back to the 1980s when the Internet Assigned Numbers Authority (IANA) was established to manage domain name systems. At the same time, the International Organization for Standardization (ISO) had developed a list of two-letter country codes as part of the ISO 3166 standard. Recognizing the potential, IANA decided to utilize these country codes to create country-specific domain extensions.

The first ccTLDs were established based on this framework, with countries such as Australia receiving “.au,” Germany receiving “.de,” and France receiving “.fr.” As the internet expanded globally, more countries and territories attempted to find their unique ccTLDs, and the decentralized model allowed individual nations to have authority over their own domain extensions.

Over time, the number of ccTLDs grew, reflecting international participation in the internet. Today, hundreds of ccTLDs represent countries, territories, and regions all over the world, serving as digital identifiers and symbols of national identity.

Numerous improvements in the global internet infrastructure led to the introduction of internationalized domain names (IDNs), which allow the use of non-Latin characters in ccTLDs. This made the internet more available for non-English speakers, enabling countries to use their native scripts in their domain extensions.

List of Popular ccTLDs

Here is a list of the most commonly used ccTLDs. They are the following:

Unique Stories

Every ccTLD has some kind of fascinating story behind it, reflecting the rich cultural diversity and national origin of the respective countries. Let’s explore a few interesting examples:

• .uk (United Kingdom): The .uk ccTLD originated from the Latin phrase “unitas katholica,” meaning “universal church.” However, it later evolved to represent the United Kingdom and its digital presence.
• .tv (Tuvalu): Tuvalu, a small Pacific island nation, entered into a partnership with a company called DotTV to market its ccTLD for use in the television and media industry. Today, .tv is a popular domain choice for multimedia websites.
• .io (British Indian Ocean Territory): Despite being a low-populated territory, the .io ccTLD has gained popularity among tech startups and online communities due to its similarity to Input/Output, a commonly used term in computing.

The Importance of ccTLDs

Country code Top-Level Domains (ccTLDs) hold significant importance in the online world for several reasons, which include the following:

• Geographic Relevance: ccTLDs offer a strong sense of geographic relevance, instantly connecting businesses with a specific country or region. This can be highly advantageous for companies that primarily operate within a precise market, helping them build trust and credibility among local consumers.
• SEO Benefits: Search engines often prioritize localized content in search results. By utilizing ccTLDs, businesses can improve their chances of appearing higher in country-specific search engine rankings. This localization factor can significantly impact the organic traffic and visibility of companies targeting specific regions.
• Localized Marketing: Country-specific domain extensions provide an excellent opportunity for businesses to tailor their marketing efforts to precise target countries. By using a country TLD, companies can create region-specific campaigns, landing pages, and promotions, effectively engaging local audiences and driving conversions.
• Brand Protection: Registering TLDs related to your business helps protect your brand from misuse and domain squatting. Securing relevant ccTLDs can prevent competitors or malicious entities from exploiting your brand’s identity and reputation.

Challenges

While ccTLDs offer numerous advantages, there are also challenges that website owners and businesses should consider:

• Limited Global Reach: Using a ccTLD might indicate that your website primarily targets a specific country or region. If you plan to expand internationally in the future, you may need to implement additional strategies like subdomains or gTLDs (generic Top-Level Domains).
• Legal and Compliance Considerations: Different countries have different legal and compliance frameworks for websites operating under ccTLDs. This includes data protection laws, consumer protection regulations, and intellectual property rights. Ensuring compliance with these requirements can be demanding, especially for businesses with a multi-country online presence.
• Domain Availability: Some ccTLDs have stricter registration requirements, leading to limited availability. As a result, securing a preferred ccTLD might be challenging for certain countries.
• Technical Limitations: Some ccTLDs may have technical limitations or restrictions compared to gTLDs. For instance, certain ccTLDs might not support specific website functionalities or have limited integration capabilities with certain platforms or tools. This can impact the overall user experience and functionality of your website.

Considerations when choosing a ccTLD

Here are several things you should keep in mind if you are preparing to use country TLDs:

• Local Regulations: Different countries may have specific requirements or restrictions when it comes to registering and using ccTLDs. It’s essential to familiarize yourself with the regulations of the target country to ensure compliance.
• Language Considerations: Some ccTLDs may use non-Latin characters, opening up possibilities for websites in languages other than English. This can be advantageous for businesses targeting non-English-speaking markets.
• Market Perception: Before selecting a country-specific TLD, consider how it might be perceived by your target audience. Some Top-Level Domains may have specific purposes or provide trust and authenticity among consumers within a particular market.

Conclusion

Building trust and credibility is vital for brands that want to succeed in today’s competitive digital landscape. By adopting country-specific top-level domains (ccTLDs), businesses can establish a strong local presence, enhance user experience, and differentiate themselves from competitors. Country code TLDs not only improve search engine rankings but also demonstrate a commitment to serving local customers at the highest possible level. To maximize the influence of ccTLDs, companies should carefully consider domain availability and protect their brand. By using the power of ccTLDs, organizations can effectively build trust and credibility while nurturing valuable relationships with their target markets.

What is Domain flipping?

Domain flipping is the term used for the business of buying potentially profitable domains and re-selling them afterward for a profit. This practice is similar to real estate flipping, where investors buy properties to sell them at a higher price. There are plenty of available domains thanks to the many domain extensions (TLDs) that have appeared recently, such as .com, .net, .org, and other ones like .tech, .shop, .online, etc. These extensions provide a wide array of options for domain flippers to explore.

You can search between them and get the domains that you think you can make a profit from. Successful domain flipping requires understanding market trends, recognizing valuable keywords, and predicting which domain names will be in demand. The process involves not only purchasing domains but also marketing them effectively to potential buyers. By leveraging tools and strategies to identify high-potential domains, domain flippers can maximize their returns and turn a modest investment into significant profits.

How to start Domain flipping?

Here are some of the essential steps in the process of flipping domains:

• Step 1 – Budget

Think about how much money you are planning to spend. Do you want to buy many domains and sell them with little earnings or do you want to try to sell domains with higher hopes? If you are starting and you are planning it as a side business, you will probably be better if you get fewer domains and for a shorter period.

• Step 2 – Niche

Do you have expertise in a particular area? Do you have an idea for an awesome domain name that nobody has seen yet? Use it! It might not be the domain with the highest search volume, but it might be perfect for a specific market or region. Even if the domain you were thinking about was taken, knowing niche specific keywords could lead you to success.

• Step 3 – Find the most wanted keywords and phrases.

To get more money for the domain you are selling, you must find desirable names. You can use a paid SEO tool or the free Google Keyword Planner to find the most searched words and phrases. The more monthly search a keyword has, the better chance you have to sell it for more.

• Step 4 – Build a portfolio of domains.

Trying your luck with just a single domain name might not be the right strategy. Try to buy at least a few similar domains. This way you can show a whole portfolio of related domains to your potential clients. They might be so interested that they can buy you more than one at the same time.

• Step 5 – Bring it to the public.

Now that you already have your domain names, it is time for the world to see them. Find domain-related forums where you can advertise them, or you can use social networks to promote the domains you have. You can also use search engines if you are betting for a significant profit. Another way to find buyers is on Reddit. There you can find plenty of interested people. If you want, you can put your domains on an auction site. There are plenty of auction sites specifically to sell domain names. Just be careful with the terms and conditions of those sites because they might have a commission. Here are a few that you can check – NameJet, Sedo, and Flippa.

• Step 6 – Be patient.

It might take time until somebody shows interest. Keep calm and continue with your marketing activities to advertise your domains. If you have interesting and attractive domains, there will be potential buyers. It is like fishing.

• Step 7 – End of the process

Ok, so you managed to sell your domain or domains, what now? It is time to control the process. Did you earn as much as you like and how much time it took you? If you are happy with the process, think if you want to repeat it with more and If you are not, quit it or change the strategy. It is a hard business that could take a long time to get it right.

Advantages of Domain flipping

It’s important to note that Domain flipping comes with risks and challenges. Yet, it can be highly beneficial for many. Here are some of the main advantages it provides:

• Potential for high returns: It can be profitable if you are able to recognise valuable domain names and sell them at a higher price. Some domain names have sold for millions of dollars, making it a potentially profitable investment.
• Minimal investment: Unlike other investment forms, Domain flipping requires a relatively low initial investment. Domain names can be purchased for as little as a few dollars, allowing individuals with limited capital to participate in this market.
• Passive income potential: Once you have valuable domain names, you can earn passive income by parking the domains or displaying relevant advertisements on them. This means that even if you are not actively selling the domain, you can still generate revenue from it.
• Diversification: Domain flipping provides an opportunity to diversify your investment portfolio. It can complement other investment strategies you may have, such as stocks, real estate, or other online ventures.
• Scalability: Domain flipping is scalable, meaning you can start small and gradually expand your portfolio as you gain more experience and resources. You can buy and sell multiple domain names simultaneously, increasing your chances of finding lucrative opportunities.
• Flexibility: You can do it from anywhere with an Internet connection, making it a highly flexible business. Additionally, it doesn’t require significant operational costs or infrastructure, reducing the overhead expenses.

What should you know before buying and selling domains?

Many people think just about the price in which they get the domain name and the one they are selling it, but that is not all. You should think about the price of your work too. How much time are you spending to get the profit? Put it in the calculation.

Check if you can legally buy and sell domains. What kind of registration must you have to do in your country? Can you receive money from other countries or not? Do you need an accountant or not?

It might not be a sustainable business. Like many other freelance activities, it might not give you a steady income every month. You might get much money with one domain and later nothing for a long time. If it is your only income, plan your expenses carefully.

Legal and Ethical Considerations

Domain flipping can be a profitable venture, but it’s important to navigate legal and ethical considerations carefully to avoid issues.

Cybersquatting Laws

Cybersquatting is illegal and involves registering domains with the intent to profit from trademarks owned by others. Always check for trademarks before purchasing a domain to ensure you aren’t infringing on anyone’s intellectual property rights.

Intellectual Property Rights

Respecting intellectual property is crucial. Conduct thorough research to avoid violating trademarks and be transparent if approached by a trademark owner.

Ethical Practices

Maintain fair pricing and honest marketing. Avoid registering offensive or misleading domain names to build a positive reputation.

Legal Registration and Taxation

Ensure your domain flipping activities comply with local business registration and tax laws. Keeping accurate financial records and consulting with a professional can help you stay compliant.

What is domain registration?

Domain registration is the crucial process of reserving and owning a unique website address, known as a domain name. It establishes your online identity, allowing you to build a website and create an online presence that aligns with your brand, business, or personal endeavors. By registering a domain, you gain exclusive rights to use that address, ensuring that your website is easily accessible to visitors across the internet.

Why is domain registration so important?

Domain registration is of utmost importance as it lays the foundation for your online presence. Here’s why it holds such significance:

• Digital Identity: Your domain name serves as your unique online address, representing your brand, business, or personal identity on the internet. It allows users to find and access your website easily, establishing your presence in the digital realm.
• Brand Recognition: A well-chosen domain name enhances brand recognition. It becomes a memorable part of your brand identity and helps customers associate your website with your business. A strong domain name can contribute to building trust and credibility among your target audience.
• Online Accessibility: Registering a domain ensures that your website is accessible 24/7 from anywhere in the world. It allows users to visit your site, learn about your products or services, and engage with your content at their convenience, expanding your reach and potential customer base.
• Professionalism: A customized domain name adds a professional touch to your online presence. It distinguishes you from competitors and demonstrates a commitment to establishing a reputable brand. It provides an impression of legitimacy and seriousness to visitors and potential customers.
• Brand Control: Registering your domain name gives you complete control over your online brand. It prevents others from using the same domain, protecting your brand identity, reputation, and customer base. It also allows you to tailor your website and email addresses to align with your branding strategy.
• Search Engine Visibility: A relevant domain name that includes keywords related to your business can positively impact your search engine visibility. It can improve your website’s ranking in search engine results, increasing organic traffic and enhancing your online discoverability.

Furthermore, note that the domain name will represent you in front of all your clients. It must be well-written, and it should be easily relatable to your brand.

It is not easy to change it. You might think, “If I don’t like I will just buy another one.” It is not that simple. Yes, the domain registration is fast, and you can buy another domain, but you will need to pay for SEO services. You will need to redirect all of the old links to the new one, and still, you will lose your position on the search engines. They don’t like new domains.

Tips to choose a domain name

• Branding. Choose a name that really represents your brand. There are many top-level domains there so pick one, where you can register your domain with your brand name spelled right. Bad orthography can really affect you negatively.
• Be short and clear. You want to explain everything, but the domain name is not the place. It must be easy to remember and write. You can always add extra details on your “About us” page.
• Choose the right top-level domain (TLD). TLD is the part after the dot like com, net, org and more. If your business is local, choosing country code domain (ccTLD) is a right decision. If your business operates in the European Union, .eu is a good chose. For the international companies, the most common choice is com, net or org. However, the name you want might not be available. Check a TLD that represent you correctly.
• Limitations. Many of the domain, especially country domain, can be registered only by people who are citizens of the particular country. There might be other limitation depending on the kind of organization you have.
• Take care of copyright problems and famous international brands. Your business might be well-known in your country, but there can be a more significant international brand that has the same name. Try to evade conflicts and lose in the search result by adding an element to concretize your business like city or country abbreviation.
• Brainstorming. You might have few ideas already, but it could be tough to choose. Make a brainstorming with your team. See what kind of suggestions they have and analyze the results. This can help you figure out the best name.

Creative alternatives when your preferred domain is taken

Finding that your preferred domain name is taken can be disappointing, but there are several creative strategies to consider:

• Modify the Original Name: You can make small adjustments to your desired domain name. For instance, if “BakeShop.com” is unavailable, consider variations like “JustBakeShop.com” or “BakeShopOnline.com.”
• Explore Alternative TLDs: If your preferred .com domain is taken, look into other Top-Level Domains (TLDs) that might be a good fit. For example, a tech company called CloudServices might opt for “CloudServices.tech” or “CloudServices.io” if “CloudServices.com” is taken.
• Integrate Keywords: Adding industry-specific keywords not only makes your domain unique but also improves SEO. For instance, “exampletechsupport.com” could be an alternative to “exampletech.com.”
• Acronyms and Abbreviations: If your business name is long or commonly referred to by initials, using an acronym can be an effective alternative. For example, “International Business Machines” could be shortened to “IBM.com” if not already taken.
• Domain Auctions and Marketplaces: Some domains are sold by owners in auctions if they are highly sought after, which might be a viable option if you are committed to a specific name.

Which is the best TLD for your businesse?

When it comes to selecting the most suitable top-level domain (TLD) also known as domain extention for your business, certain options are particularly popular and widely recognized. Here’s a guide to help you make an informed decision:

1. .com: The .com TLD is the most widely used and recognized domain extension globally. It is suitable for businesses with an international focus and offers a broad reach across different countries and industries. Consider .com if you seek a widely recognized and established TLD for your business.
2. .co: The .co TLD has gained popularity as an alternative to .com. It is often associated with “company” or “commerce” and can be an excellent choice for businesses that want a shorter and more memorable domain name. The .co TLD offers a global appeal and is widely recognized, making it suitable for various industries and businesses.
3. .io: The .io TLD has gained popularity among tech startups and businesses in the technology sector. It has a tech-savvy connotation and can be an excellent choice if your business operates in the technology, software, or startup space.
4. .org: The .org TLD was initially intended for nonprofit organizations but has expanded to encompass various entities, including businesses that focus on social causes or community initiatives. If your business has a strong social or nonprofit element, choosing .org can align well with your mission.
5. .net: The .net TLD was originally intended for network infrastructure but is now widely used by various businesses. It can be a suitable alternative to .com, especially if your desired domain name is not available with a .com extension.
6. Country Code TLDs (ccTLDs): Country-specific TLDs, such as .us for the United States or .uk for the United Kingdom, can be advantageous for businesses with a local or regional focus. Using a ccTLD helps establish a strong connection with customers in specific countries and can enhance local trust and credibility.

Remember, popularity should not be the sole determining factor in choosing a TLD. Consider your business’s specific needs, target audience, and branding requirements. Conduct thorough research and consult with experts if necessary to make an informed decision about the best TLD for your business.

The Role of Domain Security Measures

Effective security measures are crucial for protecting your domain and ensuring a safe browsing experience for your users. Here’s a concise overview of essential security practices:

SSL Certificates
Secure Sockets Layer (SSL) certificates are vital for any website, encrypting data transmitted between the site and its visitors. This encryption helps secure sensitive information from interception and misuse, boosts search engine rankings, and increases user trust, as browsers typically mark secure sites with an SSL certificate as safe.

DDoS Protection
Distributed Denial of Service (DDoS) protection is essential to safeguard your website against attacks that attempt to overwhelm it with excessive traffic. DDoS protection services differentiate between legitimate user traffic and attack traffic, allowing your site to remain operational and accessible even under attack.

Comprehensive Security Practices
Beyond SSL and DDoS protection, consider the following practices to enhance your domain’s security:

• Regular Updates: Maintain security by regularly updating website software and scripts to protect against vulnerabilities.
• Strong Access Controls: Use robust passwords and multi-factor authentication (MFA) for all related accounts to enhance security.
• Backup Solutions: Implement regular data backups to quickly restore your website if needed.
• Network Security Measures: Utilize firewalls and other network security tools to prevent unauthorized access.

These streamlined security measures ensure that your domain remains secure, enhancing your website’s credibility and protecting your users’ data.

The Domain Name System (DNS) is often compared to a phonebook, and there are a lot of similarities. It is another type of database. DNS is a global system that we all use on a daily basis when we want to access any website. It contains and distributes information about domain names and their corresponding IP addresses. This way, when we type a simple domain name, our browsers or application will use the DNS to search for its IP address and connect us. The DNS is divided into domains from different levels, and it is managed through DNS zones that are decentralized. An administrator of a higher level can delegate a zone to another under it. For example, when you get a domain name (secondary-level domain like yoursite.com), the higher level .com (TLD) can delegate you the right to manage the zone yoursite.com. You can further delegate responsibility for all subdomains like mail.yoursite.com, ftp.yoursite.com, etc. To manage domain names, you add DNS records, which are a set of instructions related to your domains, hosts, services, and more.

Domain Name System explained

List of DNS terms

Here you have the most important DNS terms that you will need to manage your domain name. First, you can learn the basics of DNS, and later you can expand your knowledge with larger articles that go into greater details on topics like DNS records, DNS features, and processes. 

Domain Name

It’s an identifier of a host, a text line, that servers for mapping to an IP address (a line of numbers like: 46.166.142.62) for easy access to a website. By now, you have typed a lot of different domain names in the URL bar of your browser to reach different websites. Example: cloudns.net

Machines have always searched websites through their IP address. Numbers are the best way for machines to understand each other. But numbers are hard to be remembered by humans. That’s why domain names were created. To have a friendly choice for humans to reach the websites they look for.

IP Address

An Internet Protocol address is another host identifier that is created of a line of numbers divided into groups by periods. Example: 46.166.142.62. IP addresses are needed so devices can connect to networks and communicate using the Internet Protocol (IP).

The set of numbers on every public IP address is mathematically generated and allocated by the Internet Assigned Numbers Authority (IANA). An entity of the Internet Corporation for Assigned Names and Numbers (ICANN).

Basically, IP addresses allow the identification, location, and communication of hosts on a network. Every device uses a unique IP address. This way, the Internet and networks, in general, can distinguish all the websites, routers, connected computers.

Many IPv4 addresses are still in use, but the latest standard IPv6 is growing in popularity.

TLD (Top-level Domain)

Domain names have a hierarchy structure. The top-level domain is one of its parts, and it’s located, reading from right to left, just after the final dot for the root and before the secondary-level domain name. Examples: .com, .gov, .uk, .ru, etc.

Initially, TLDs were created to organize domain names by their purpose, geographical location, field, operation radius. By only reading this part of a domain name, users could also know if a website they visited belonged to a commercial, government, non-profit organization, operating regionally, locally, internationally, and so on.

In the beginning, this use was more strict. In 2010, the Internet Corporation for Assigned Names and Numbers (ICANN) accepted the creation of new, generic, trademark TLDs. Now, TLDs are chosen to obey Marketing objectives too.

FQDN (Fully Qualified Domain Name)

It’s the most complete domain name that hosts can have. It points to the exact location of a domain name in the domain name system (DNS) tree hierarchy. This is expressed through the three parts that shape every domain name: hostname, second-level domain name, and top-level domain name (TLD). Following this structure, here you have an example: www.cloudns.net.

Anycast DNS

Anycast DNS is a traffic routing method where the same IP address is used for multiple nameservers located in different locations. Usually, there are many locations (points of presence) – at least 20 for a well-sized DNS provider. Having a large number of servers makes Anycast DNS resistant to DNS attacks and provides redundancy in general. 

When a client request a domain, the router will direct its request to the nearest nameserver. This will reduce the latency and offer a better experience for the clients.

Dynamic DNS

Dynamic DNS, also known as DDNS, is an automatic method of updating nameservers. The most common use case is to update IP addresses that are contained in A records (IPv4) or AAAA records (IPv6) when a change has occurred. It is particularly useful for CCTV cameras or remote services because with Dynamic DNS, you don’t need to pay for static IP addresses. The IP addresses will change over time, but they will be updated, and you won’t experience problems. After the initial setup process, you don’t need to interact with the settings, and it will continue to function.

DNSSEC

DNSSEC is a security extension that has the goal to protect DNS communication and stop DNS spoofing. It encrypts the DNS communication with a combination of private and public keys. One that the zone administrator uses to sign it and the other for authentication of the origin of the data. What makes it a good protective mechanism is that it is a complete chain of trust. Starting from the root zone down to the TLD zone, the domain zone, and subdomains, each zone above will have the key for the next one. It adds security to the fast DNS process without a significant slowdown.

DNS Server (types)

There are different DNS servers, and each has specific functionality.

Root server. It belongs to the highest level of DNS servers. It’s the authoritative name server for a specific DNS root zone. It points to the TLD of the requested domain name.

TLD server. It’s responsible of specific TLDs (.com, .gov, .uk, .net, etc.). It will point to the exact, authoritative name server that can provide the IP address for the requested domain name.

Recursive DNS server. The server takes the user’s DNS request and looks for the IP address or other information needed for the requested domain name. It will communicate with all the other DNS servers in the hierarchy for getting this information.

Authoritative DNS server. It contains all the DNS records for the zone it’s in charge of. It answers the requests that recursive DNS servers have by providing the corresponding A or AAAA record and the IP address of the requested domain or another DNS record.

Primary authoritative DNS servers. They answer DNS requests, and they store the original zone file. Therefore, DNS records’ modifications can only be made on these servers. 

Secondary authoritative DNS servers. They also respond to DNS requests, but what they store is a copy of the zone file. This copy is not editable at all, only readable. 

DNS Zone

The DNS system has a structure that looks like an inverted tree. It is divided into domain names on different levels. The highest level is the root, after many TLDs, secondary-level domains, and later multiple levels of subdomains. To administrate those domain names, there are DNS zones on each level. The DNS zones are partitions of the Domain Name Space that contain DNS zone files with DNS records for managing. A DNS zone administrator can add or remove DNS records inside the Primary DNS zone.

DNS records

DNS records are simple files that contain text with instructions related to the domain name they belong to. They can link domain names to IP addresses, add instructions for email servers, point to specific services, and much more. The DNS records are hosted inside a host file in a DNS zone. The zone is located inside an authoritative nameserver.

There are many types of DNS records, but the most popular ones are:

A record – Links a domain name to an IP address. 

CNAME record – Forwards subdomains to the domain name.

MX record – Indicates the email servers that should receive emails for the domain name.

TXT record – Multiple verifications and authentication purposes.

NS record – Shows the nameservers for the domain name.

SOA record – Start of authority.

SRV record – Links services to port numbers.

PTR record – The Pointer record links an IP address to a domain name.

The Importance of DNS Terminology

Understanding DNS terminology is crucial for various reasons, including the following:

• Efficient Troubleshooting: Solid knowledge of DNS terms allows IT professionals to diagnose and resolve technical issues more efficiently. Identifying the root cause of problems, such as domain resolution failures or misconfigured DNS records, becomes significantly easier and faster.
• Enhanced Security: Cybersecurity is a top priority nowadays. Therefore, it is best for professionals to understand DNS terminology in order to detect and respond to potential threats. Understanding terms like DNSSEC, DNS spoofing, cache poisoning, and DDoS attacks helps strengthen the security of networks and web services.
• Performance Optimization: Website owners and developers can benefit from understanding DNS terminology to optimize the performance of their online presence. Fine-tuning DNS settings, minimizing TTL values, and ensuring proper DNS record configurations contribute to faster and more reliable website performance.
• Effective Communication: Clear communication within IT teams, especially between developers, network administrators, and support teams, is crucial, especially when they need to communicate complex technical issues. A common understanding of DNS terms allows effective communication and collaboration within teams.
• Domain Management: Individuals and organizations involved in registering and managing domains must be familiar with DNS terminology to make informed decisions. Knowledge of terms like TLDs, registrars, and DNS hosting providers empowers domain owners to navigate the complexities of the domain ecosystem.

NXDOMAIN – Definition

NXDOMAIN stands for a non-existent domain and represents an error DNS message received by the Recursive DNS server (the client) when the requested domain cannot be resolved to an IP address. In other words, an NXDOMAIN error message simply indicates that the domain does not exist. 

You can guess that your browser landed on such errors if you notice the sad document or the cloud thought bubble. It is the direct way of the Internet of saying, “there is no answer to your query”. In technical terms, it states that the domain name specified in the Domain Name System (DNS) query does not exist. Therefore, only an Authoritative nameserver can return an NXDOMAIN answer. 

Otherwise, if the domain name exists, nameservers and Recursive DNS servers are going to work together to return the positive NOERROR response. Additionally, the precise IP address answer to the DNS query is going to be returned too. We should mention that it is possible to receive a NOERROR response without any specific answers. That appears when the domain name actually exists, but the requested DNS record type doesn’t.

Impact of NXDOMAIN Errors

Let’s talk about why those errors can be a headache for everyone involved – users and website administrators. It’s like when you’re all set for a road trip, but suddenly, there’s a detour sign, and you have to take a different route. NXDOMAIN errors are like those unexpected route signs in the digital world, messing up the plans and leaving people scratching their heads. The impact of these errors can be the following:

• For Users: So, you’re surfing the Internet, looking for something interesting, and bam! NXDOMAIN hits you. It’s like hitting a roadblock in your online journey. And you know how it feels when your favourite road is closed – frustration kicks in. Users might throw their hands up and say, “I’m out!” Plus, if it keeps happening, people start wondering if the website is having a bad day, and that’s not great for anyone.
• For Websites: Now, imagine you’re running a website or a business online. NXDOMAIN errors mean people can’t reach you. That’s potential customers lost, revenue slipping away, and your website’s reputation taking a hit. It’s like having a store with a “Closed” sign on the door – not a good look! Search engines also notice when your site isn’t playing nice, affecting how easily people find you online. And, let’s be honest, if customers can’t rely on your website, they might start looking elsewhere.

NXDOMAIN on different browsers

Every day users surf via different web browsers, and DNS (Domain Name System) is responsible for connecting the requested domain names to the corresponding IP addresses (IPv4 or IPv6), a process also known as DNS resolution. If the process is successful, they are directed to the desired websites. Yet, if DNS fails to connect a particular user, it receives the NXDOMAIN error message. 

However, every browser has its personal way of showing this error. Here is how it appears on the four most popular browsers: 

• Google Chrome: On this browser, the error is easily noticeable. A ‘DNS_PROBE_FINISHED_NXDOMAIN’ error message is actually shown on the page, plus the statement that the site cannot be reached. Through a blue button, you can try reloading the website.

• Mozilla Firefox: With this one, you see an explanation that there is a problem finding the right website and that no connection can be made to the server. Additionally, there are three simple suggestions for solving the problem, plus a reload button.

• Microsoft Edge: It informs that ‘this page cannot be reached’. Here you also have several suggestions for solving the problem.

• Safari browser: On this browser, you only receive the statement ‘Safari can’t find the page (exampledomain.com) because Safari can’t find the server of (exampledomain.com)’.

How do users trigger NXDOMAIN? 

The NXDOMAIN error message is not a great and desired thing to see. However, it can be useful for exposing criminals attempting to steal your organization’s intellectual property.

Internal NXDOMAIN answers appear when a DNS (Domain Name System) holds no listing for the requested domain. A user on the network can trigger an NXDOMAIN for the following reasons:

• The user enters a typo when attempting to visit a particular website.
• The client’s application has an incorrect configuration.
• A web browser accesses random local domains on startup to try to detect hijacking behavior.
• The device is infected with a bot using a domain-generating algorithm (DGA) to take part in a botnet.

What does it indicate?

Constantly receiving NXDOMAIN messages can be an early indicator of network problems or security gaps. So, to examine DNS error replies to find security and network performance issues, you would need complete data from DNS logs. By analyzing the data, you can discover more details about the core reason for the failed DNS requests.

Here’s what it can indicate:

• Beaconing

Malware beaconing allows cybercriminals to understand they’ve successfully infected a system. Afterward, they can send commands and initiate a malicious attack. Commonly it is the first sign of Distributed Denial-of-Service (DDoS) attacks.

The host infected with malware utilizes regular DNS requests in order to hide its beacon. As a result, the signals between the malware and the command-and-control server (C2) look like regular network communications. Therefore, frequent NXDOMAIN responses can indicate that a host is infected. 

• Reconnaissance and lateral movement

Many advanced persistent threats often act at the back of a network. They remain and search for sensitive information and methods to exfiltrate data to the outside. Yet, this mapping process usually includes a large amount of trial and error. 

Constant NXDOMAIN replies from your local DNS service, where each of them originates from one client, could be an indicator.

• Issues with DNS zone sync

DNS zones are commonly duplicated in multiple servers to minimize latency and improve reliability. As a result, some users will still get the correct response in case these zones fall out of sync. Yet, others will receive an NXDOMAIN error message for the exact same destination. It all depends on the DNS resolution path. 

Often such cases are quite difficult to debug without any visibility into the internal network traffic. Network admins must trace exact pathways between clients, networks, and servers.

What is the difference between NXDOMAIN and SERVFAIL?

Both NXDOMAIN (Non-Existent Domain) and SERVFAIL (Server Failure) are response codes in the Domain Name System (DNS). However, they indicate completely different types of errors.

• NXDOMAIN (Non-Existent Domain): It signifies that the queried domain name does not exist. The Recursive DNS server searched for the requested domain name, but it didn’t find DNS records associated with it. It indicates that the domain name you’re trying to access doesn’t exist on the Internet.
• SERVFAIL (Server Failure): This response code indicates that there was an issue or failure in the DNS server’s ability to fulfil the DNS request properly. It indicates that there might be a problem with the DNS server itself or its ability to communicate and process the query effectively. SERVFAIL can occur due to various reasons, such as misconfiguration, network issues, or the DNS server being overwhelmed.

In summary, NXDOMAIN indicates that the queried domain doesn’t exist, while SERVFAIL indicates a failure or problem with the DNS server itself when trying to process the query.

What is an NXDOMAIN attack?

The NXDOMAIN attack is a DNS Flood Attack that involves many DNS lookup requests sent to non-existent domain names, commonly subdomains of the primary domain under attack. These requests are forwarded to the Authoritative DNS server, responsible for the domain name, intending to reach its resource limit. As a result, the server becomes incapable of responding to legitimate requests, making the victim’s website inaccessible to users.

The majority of these attacks are carried out by botnets, which makes the NXDOMAIN attack pretty hard to detect and block.

Detection and prevention of an NXDOMAIN attack

There are some unsophisticated NXDOMAIN attacks that could be more easily detected, like, for instance, catching an out-of-the-ordinary number of requests to non-existent domain names from just one source.

Unfortunately, these attacks are typically initiated with the help of numerous infected devices (botnet) that make their detection way more complicated. They are considered more sophisticated attacks that have the potential to blend in legitimate requests, and noticing them is very challenging. The key to detecting these attacks is to collect and analyze large amounts of data for the patterns of abuse.

The prevention of NXDOMAIN attacks is a pretty tough assignment. However, it all comes down to having large and even excess capacity in order to handle a sudden spike in traffic, plus catching and blocking DNS requests by non-legitimate sources.

Anycast DNS is very helpful in balancing the load, and it will keep your website up and running. Additionally, DNS monitoring and some firewall products are available for examining and protecting a particular network.

Conclusion

So, now you understand what actually NXDOMAIN error message is and how it looks in your browser, and you can easily identify it. Sometimes it can be an everyday problem with an easy fix, while in other cases, it could be a true indicator of a malicious threat. By analyzing and understanding the root cause, you can eliminate potential attacks. Additionally, it is best to implement measures that can help you detect and block NXDOMAIN attacks.

What is FQDN?

The popular acronym FQDN stands for Fully Qualified Domain Name. It represents the fullest possible domain name of a host or a computer on the internet. In addition, it could be related to a website or to a server. 

As you probably know, the Domain Name System (DNS) is decentralized, and it is built in a very precise hierarchical order. The Root is the beginning and above everything else, and one level below is the Top-Level Domain (TLD). The following component in the hierarchical order is the domain, and finally, the last important element is the precise hostname.

• FQDN Syntax

Here you can see the syntax of it:

[hostname].[domain].[tld]

It can also include a subdomain. Yet, you should know that the subdomain is not the hostname. It is just a part of the domain. 

• FQDN Example

Let’s see an example of FQDN using cloudns.net. We read it from right to left.

www.cloudns.net

First is “.net“, which is the Top-Level Domain (TLD). Then it follows the domain name “cloudns“, and the last is the hostname “www.“. 

The hostname can show a specific service or protocol for the domain like “mail” or “ftp”.

The FQDN serves to show the exact location of an object inside the DNS hierarchy.

Structure and elements of FQDN

The Fully Qualified Domain Name (FQDN) actually has a very simple and easy-to-understand structure and three main elements. So, let’s explain a little bit more about them:

TLD (Top-Level Domain): It is shown with all of the standard extensions that are located at the very end of an FQDN. They usually are very short, and their length is just 2 or 3 letters. Some popular examples are .com, .edu, .uk, etc. Of course, in the present days, you can find TLDs that are a little bit longer than that. For instance, there are .systems, .company, etc.

Domain: It stands exactly after the Top Level Domain (TLD) and is very well-known, and regular users are familiar with it. Here is a simple illustration – example.com.

Hostname: You can also identify it with ease. It is represented by the symbols at the very beginning of the Fully Qualified Domain Name (FQDN). Here a widespread and familiar example is www in www.example.com. Some domain owners could create different hostnames based on the need of their domain name. Each of them is going to be related to the domain. Several examples of such different hostnames are:

• www.example.com
• ftp.example.com
• mail.example.com

What is PQDN?

The short acronym PQDN stands for Partially Qualified Domain Name and it simply represents an FQDN (Fully Qualified Domain Name) with a missing part. It does not include all of the elements that provide the precise position on the DNS hierarchy. It is just a part of the complete domain name. 

To make things more simple, let’s use the ClouDNS domain name again for an illustration. The PQDN is, for example, “cloudns.net“. In this one, we don’t have the host “www.“.

Many users use PQDN daily without even knowing it. The reason for that is simple. PQDN is more accessible and easy to use. In addition, it is shorter, which makes daily searches quicker and easier.

If you are searching for a fast and secure DNS service – the best choice is the Anycast DNS!

How to make a FQDN lookup?

You can perform an FQDN lookup on your computer with any of the popular operating systems (OS).

Windows 10

Here is how to see the FQDN on a Windows 10 device:

1. Click on the Start menu, type “Control Panel,” and click it. 
2. Inside the Control Panel, find “System” and open it. 
3. Inside the System, look for “Device specifications” and search for the “Full Computer Name.” 
4. There is the FQDN. 

macOS 

If you are using macOS, follow these next steps to find the FQDN.

1. Open the Terminal application.
2. Inside, type the following command: “hostname -f” and press the Enter button. The option “-f” means full. 
3. You will see the FQDN. 

Linux 

If you are a Linux user, you can find the FQDN similar to the macOS.

1. Open the Terminal application. 
2. Inside, type the following command: “hostname -A” and press the Enter button.
3. You will see the FQDN. 

Why do you need FQDN?

Here are some of the main cases when FQDN comes in hand:

• You will need FQDN to make a device accessible on the internet. You will use it to configure your DNS and get an IP address.

• Another use case is when you want to get an SSL certificate. Today, almost every site has one, and you need to provide the FQDN to obtain it.

• Remote Access. The DNS server will perform a lookup in its registers and resolve the FQDN to the correspondent IP address.

• Access a protocol or a service. If you want to use a FTP for example, you will need the Fully Qualified Domain Name or IP. Also, for setting up email for specific applications, you will need it.
• Network management: FQDNs are crucial in large networks for segmenting and managing different zones efficiently, ensuring secure and organized traffic flow.
• API access: In cloud computing and web services, FQDNs are key for identifying and accessing API endpoints, enabling smooth communication between software systems.

FQDN vs URL: Are they the same thing?

In the technical realm of internet architecture, the terms Fully Qualified Domain Name (FQDN) and Uniform Resource Locator (URL) are often conflated, yet they serve distinct roles. An FQDN represents a complete and precise domain name, providing an exact location in the Domain Name System (DNS) hierarchy. This includes the top-level domain and all subordinate levels. In contrast, a URL is a comprehensive descriptor used to locate a specific resource on the internet. It includes the protocol (e.g., HTTP/HTTPS), the FQDN, and additional components like resource path and query parameters. While an FQDN is a critical part of a URL, delineating the domain aspect, a URL extends this concept to encompass the full path necessary for accessing a particular internet resource. Understanding these nuances is crucial for professionals dealing with web development, networking, and IT infrastructure.

Conclusion

In summary, Fully Qualified Domain Names are an essential aspect of internet navigation and domain management. They provide a detailed and specific way of identifying and locating computers or services within the vast network of the internet, ensuring precise and reliable connectivity. Understanding FQDNs is crucial for effective domain setup and management, making it a fundamental concept for anyone working with or interested in the digital domain space.
