What is a DDNS (Dynamic DNS)?

DDNS, most commonly known as Dynamic DNS, is an automatic method of refreshing a name server. It can dynamically update DNS records without the need for human interaction. It is extremely useful for updating A and AAAA records when the host has changed its IP address.

Imagine this situation. You have a server in your office, and you are providing some service to your employees. You are using a standard/consumer-grade internet from a typical ISP (Internet service provider). You are getting a temporary IP address that could change the next type you connect or change automatically after some time. To provide a service, you 3 options:

1. A Static IP address that could be expensive.
2. Change the IP address manually every time it changes
3. Automatically update the IP addresses – Dynamic DNS or DDNS!

DDNS is a service that automatically and periodically updates your DNS’s A (IPv4) or AAAA (IPv6) records when your IP address changes. These IP changes are made by your Internet provider.

With DDNS you don’t need to worry about the changes in IP addresses!

In this article, you can find more information about what DNS is!

How does DDNS work?

The DDNS works in the following way: The DDNS client monitors the IP address for changes. When the address changes (which it will if you have a dynamic IP address), the DDNS (or Dynamic DNS) service updates your new IP address.

Let’s get back to the same example from before, you owning a server, connected to the Internet, and want to share service from it. 

This server will be connected to the internal network, and it will communicate with the Internet via NAT (Network Address Translation) router. The NAT router will provide an internal IP address to the server, probably via DHCP. To Make it available externally, we will need to perform port forwarding and get external Port (Portex) and external IP address (IPex). Now the service you want to share is visible with IPex and Portex, and people can use it through the Internet. The problem comes when this IP changes. 

First, you will need to register with a Dynamic DNS provider like us and set up a client software on your server. In the Dynamic DNS settings, you will give a fixed name to this server. Put the IPex, and we need to tell the NAT to automatically update it and send the data to the DNS server.  Inside the NAT’s settings, we will put the data from our Dynamic DNS service provider (our account and password). Now everything is ready.

Why is it useful?

It can be very useful for people who want to host their website, access CCTV cameras, VPN, app or game server from their home computer. It is cheaper than to have a static public IP and by setting up DDNS, you will avoid the need to update all of your records whenever your IP changes manually. Also, a static IP address is not always an option; it depends on your Internet provider.

DDNS is a very flexible option. The way that Dynamic DNS gives a connected device the ability to notify DNS servers to automatically update, alongside the active DNS configuration, IP addresses, configured hostnames and some other information. This saves the need of an administrator who should do the changes.

Common use cases for DDNS

DDNS is a valuable tool in scenarios where devices are assigned dynamic IP addresses. Here are the key use cases:

• Home Servers: If you’re hosting a personal website, game server, or file storage at home, DDNS ensures you can always access your server via a fixed domain name, even if your IP changes regularly.
• Remote Access to Security Cameras: Many people use DDNS to view their home CCTV cameras remotely. Instead of updating the IP address every time it changes, DDNS keeps the connection steady through a permanent domain name.
• VPN and Remote Desktop: Whether for work or personal use, accessing a home or office network remotely via VPN or remote desktop is easier with DDNS, allowing uninterrupted connections despite changing IP addresses.
• IoT and Smart Home Devices: DDNS is often used to manage smart home systems or IoT devices. It ensures that even when your home’s IP changes, you can always reach devices like smart lights, thermostats, and more from any location.
• Game Servers and Media Streaming: Hosting a game or media server at home? DDNS provides consistent access for friends or family to your server, regardless of your ISP changing your IP.

By automating IP updates, DDNS saves you the hassle of manually tracking and updating IP changes, offering convenience and cost savings compared to static IPs.

Benefits

As you can see DDNS is a very convenient solution, and it has different advantages, but the main ones are the following:

Accessibility – You will be able to access your website or server, easily, without being worried. The IP will change, but this won’t stop any of your activities.

Practicality – You don’t need a network administrator to check and reconfigure your settings.

Economic – DDNS makes it cheaper; you won’t have IP address conflict in case you have many addresses, and they are used at the same time.

There are many other advantages, and you are probably thinking about how to start using DDNS. Luckily for you, it is relatively easy to switch to it. You can get a free DDNS service from ClouDNS.

What is rDNS?

You probably already know what a forward DNS is. It links the associated hostname/domain to the IP address. Now think from the opposite direction. rDNS, also known as Reverse DNS, is doing the mirror action, using the IP address to find the hostname/domain name. You might be surprised that this is actually needed, but it has significant application. It is very useful for email verifications B2B and troubleshooting.

Imagine this situation, you don’t have a reverse DNS set up, but you are sending a very important email to another company. They have a mail server with Anti-Spam protection. It will check if you have rDNS and if you are missing it, your message will go directly to the spam bin. This protection reduces the phishing significantly by putting straight into the spam, all emails that have IPs that don’t correspond to IPs of the domains they say they come from.

All devices connected to the internet have their IP addresses. This makes it easy to do a reverse DNS lookup and see who it is on the other side. For this purpose, you will need a PTR record.

Why is rDNS important?

There are several reasons why rDNS is crucial. Some of them are the following: 

• Email Authentication: rDNS helps authenticate email servers and prevent spam. A large number of email servers will only accept incoming emails from hosts with a valid PTR record. That way, they avoid spam and phishing emails from spoofed IP addresses.
• Network Troubleshooting: rDNS can be used to help troubleshoot network issues. If a network administrator is trying to diagnose a problem with a specific IP address, they can use rDNS to determine which hostname is associated with it. This can help them identify the device or service causing the problem.
• Protection: Some security systems use rDNS to identify and block malicious traffic. For example, some intrusion detection and prevention systems will use rDNS to recognize and stop traffic coming from known malicious IP addresses.
• Access Control: In some cases, rDNS can be used to control access to a network or specific services. For example, some firewalls and VPNs use rDNS to allow or deny access to particular hosts or services based on their hostname.

How does rDNS work?

The main goal of rDNS is to map an IP address to a hostname. In order to achieve that, it works by performing a reverse lookup of an IP address to find the associated domain name.

The process of rDNS starts with a query to a DNS server, asking for the hostname associated with a specific IP address. The DNS server then looks up the available IP address in its records, and if it finds a match, it returns the associated hostname.

Reversing the forward DNS process and resolving an IP address to a domain name requires a Reverse DNS zone and a PTR record. So, let’s explain a little bit more about them!

PTR record

The PTR record is also called a Pointer record, and its primary purpose is to link the IP address to its corresponding hostname/domain name. It is important to note that you should have an A or AAAA record for each PTR record you create. The explanation behind this practice is pretty simple. An A record or AAAA record maps a hostname/domain name to its IP address, and PTR goes exactly in the opposite direction. That is why it is essential to ensure you configure your DNS records accurately without any mistakes. Otherwise, there is a possibility for your emails to land directly into the spam folder of your recipients.

Reverse DNS zone

Using rDNS requires creating a special type of DNS zone called a Reverse DNS zone. That is the only place where PTR records are able to exist and function correctly. Reverse DNS can work both with IPv4 addresses and IPv6 addresses, yet they should be written in reverse. That is because there is a specific root domain in-addr.arpa that uses the IP addresses in reverse order. So, for example, the IP address 111.123.101.1 becomes 1.101.123.111.in-addr.arpa.

How to start using rDNS?

The first step is to create a Reverse DNS zone; you can do that from the Control Panel, add a new zone and click on the Master Reverse DNS zone.

Watch the video to find out how to add Master Reverse DNS zone

This zone is directly related to the size of your IP network. For example in IPv4/24 network, you will have 255 IP addresses. In the network 192.168.1.0/24, all the available IPs will be from 192.168.1.1 to 192.168.1.255, and the Reverse DNS zone will have this format 1.168.192.in-addr.arpa

Now in this Reverse zone, we can add PTR records that match each IP from the network. You just add a new record; this will be for the first IP 192.168.1.1

Type: PTR

Host: 1

Points to: hostname1.example.com

The PTR records will look like this in the Control Panel:

Then, make sure that there is a matching A record. Each PTR must have one.

Find more information about PTR records and how to create them!

The last step is to change the name servers of your Reverse zone at your IP provider or ask them to do it. A configured NS records at the IP provider must point to the name servers listed in your Control Panel.

What in-addr.arpa is?

in-addr.arpa is a critical component in the architecture of Reverse DNS (rDNS), playing a pivotal role in how rDNS functions. This special domain is used specifically for mapping IP addresses to domain names, which is the essence of rDNS. Here’s a concise overview:

• Purpose: Used for IPv4 reverse DNS lookups, in-addr.arpa facilitates the conversion of IP addresses into a format suitable for DNS queries. This process is vital for various network services, especially email authentication.
• How it works: An IP address like 192.0.2.1 reverses to “1.2.0.192.in-addr.arpa“. A DNS query for this domain retrieves the associated domain name via a PTR record, crucial for verifying communication sources.
• IPv6 addresses: For IPv6, a similar domain called “ip6.arpa” is used, reflecting the distinct structure of these addresses.
• Management: Managed by IANA, in-addr.arpa’s namespace is partly delegated to ISPs for localized reverse DNS record management.

In essence, in-addr.arpa underpins rDNS, crucial for network integrity and cybersecurity efforts.

rDNS lookup – How to do it?

Now that we have explained the basics of rDNS, it’s time to show you how to perform an rDNS lookup. Besides, the process is simple, and you don’t need to have a background in IT to complete it. 

• Windows

If you are a Windows user, you can perform rDNS lookup with the NSlookup command. First, open the Command Prompt by pressing the Windows key + R, then typing “cmd” and pressing Enter. Type the following command:

$ nslookup 1.2.3.4

• macOS and Linux

If you are a macOS or Linux user, you can complete the rDNS lookup with the Dig command or the Host command. Open the Terminal application and write the following:

$ dig -x 1.2.3.4

or 

$ host -t PTR 1.2.3.4

*Please, make sure to replace “1.2.3.4” with the IP address (IPv4 or IPv6) you wish to check.

It’s important to note that in some cases, the rDNS lookup may not return any results if the IP address does not have a PTR record associated with it. Besides, in other cases, the response may show “NXDOMAIN” or “NXRRset”. Also, some firewalls or security systems may block reverse DNS queries.

Comparing rDNS and Forward DNS

Understanding the differences and interactions between Reverse DNS (rDNS) and Forward DNS is crucial in grasping internet infrastructure’s full scope.

Forward DNS is the process that converts human-readable domain names (like www.example.com) into IP addresses (like 192.168.1.1). This conversion is essential for internet navigation, allowing users to access websites without memorizing complex numeric addresses.

On the other hand, Reverse DNS (rDNS) works in the opposite direction. It takes an IP address and returns the corresponding domain name. This process is particularly important in scenarios where knowing the source of a network request is crucial. For example, when an email server receives a message, it might use rDNS to verify that the IP address of the sender matches the domain name claimed in the email. This verification helps in filtering out spam or spoofed emails.

The interaction between these two systems is symbiotic. While forward DNS is primarily used for routing internet traffic to the correct destinations, rDNS plays a key role in authentication and security. Together, they form a comprehensive system for both reaching and validating internet entities.

Conclusion

rDNS is essential for email authentication, network security, and troubleshooting network issues. It performs a reverse lookup of an IP address to find the associated hostname. To achieve that, creating a Reverse DNS zone and adding PTR records is required. Thanks to this amazing technology, the Internet is a more secure place by identifying the authenticity of the source of the email, and it is beneficial for network troubleshooting.

But first, let’s explain a little bit more about what DNS records actually are.

DNS records briefly explained

DNS records are simple text-based instructions for a specific domain name. Their main purpose is to set precise rules for the domain. Additionally, they are created and gathered in a zone file in the DNS zone. All that information is stored on the Authoritative DNS server for the particular domain name. As we mentioned, DNS records are completely made of text. Therefore, they are pretty light. That allows DNS administrators to edit and adjust them easily. 

Every DNS record type has a different function, so each of them is important for the proper management of the domain name. Moreover, when a user makes a request, the Recursive DNS servers search for a precise DNS record type. 

For the rest of this article, we are going to present to you some of the most important and interesting DNS record types. 

Common DNS record types

There are several types of DNS records, each serving a different purpose. Let’s take a look at some of the most common ones:

SOA Record

SOA (Start of Authority) shows the start of the authority DNS zone and specifies the global parameters of the zone. Every zone must have one, and you can’t add two per zone. It has the following parameters: Serial number, Primary Nameserver, DNS admin’s email, Refresh Rate, Retry Rate, Expire Time and TTL.

A and AAAA Records

These DNS record types are perhaps the most popular and also most important. The A record and the AAAA record are both responsible for mapping a domain name to its corresponding IP address. This is what enables users to access your website via its domain name. The difference is that A record points to an IPv4 and the AAAA record to IPv6.

MX Record

The MX record, commonly also known as mail exchange record, is used to specify the email server responsible for accepting incoming email messages for a domain name. This DNS record type is crucial for ensuring that your email gets delivered to the correct mail server. Basically, it says which server should receive the incoming emails. If it is not directed well, you won’t receive emails.

CNAME Record

CNAME record is another very popular DNS record type where the short acronym “CNAME” stands for Canonical Name. It allows you to point one hostname to another, not to an IP address like the A and AAAA records. You can use it when you want to create an alias for a domain name. It serves just for subdomains. It is important to note that you can add only one CNAME record per hostname.

TXT Record

The TXT record allows you to add and store text-based information about a domain name. There are all kinds of TXT records and some of them people can easily understand, and others are specifically for machines to read. For example, DKIM (DomainKeys Identified Mail) record is a TXT record that associates a domain name with a specific email message. There is also DMARC (Domain-based Message Authentication, Reporting, and Conformance) record that identifies and blocks spam and phishing emails by verifying the emails.

SPF Record

Creating an SPF (Sender Policy Framework) record shows who is authorized to send emails with a particular domain. Without it, all the emails you send will go directly to the spam folder of the recipients. It is helpful for preventing email spoofing and phishing attacks.

NS Record

The short acronym “NS” stands for Nameservers, and this NS record points the domain name to its authoritative DNS servers responsible for the DNS zone. The NS record is essential for ensuring that your domain name is properly registered and configured.

SRV Record

SRV records are responsible for defining the locations of servers for specified services, such as voice-over IP (VoIP), instant messaging, and others.

Web Redirect (WR) Record

The Web Redirect record does precisely what it says. It redirects from one address to another. There are a few types: 301 redirect which is a permanent redirect, and 302 redirect, which is temporary, if the address has been moved but not permanently. You can do such a redirection with SSL too.

ALIAS Record

ALIAS record is a very similar to the CNAME record. It allows you to add various hostnames for the same subdomain. You can use it for the root domain as well. This type of record is built into the ClouDNS.

RP Record

The RP record, or Responsible person record, shows who is responsible for the domain name and specifies its email address.

SSHFP Record

Secure Shell Fingerprint record is used for Secure Shell (SSH). The SSHFP record is typically used with DNSSEC enabled domains. When an SSH client connects to a server, he or she checks the corresponding SSHFP record. If there is a match, the server is legit, and it is safe to connect to it.

PTR Record

The PTR record, also commonly known as the Pointer record, points an IP address (IPv4 or IPv6) to a domain name. It is the exact opposite of the A and AAAA records, which match the hostnames to IP addresses. PTR records are used for Reverse DNS.

NAPTR Record

IP telephony uses Naming Authority Pointer records, or for short NAPTR records,  for mapping the servers and the users’ addresses in the Session Initiation Protocol (SIP).

CAA record

Certification Authority Authorization (CAA record) record gives the ability to the DNS domain name holder to issue certificates for his/her domain. The record can set policies for the whole domain or for specific hostnames.

Wildcard DNS Record

The Wildcard DNS record will match requests for non-existing domain names. It is specified with a “*” for example *.cloudns.net

For more information, examples, and video tutorials check the following DNS record wiki page.

How many DNS record types are there?

The Domain Name System (DNS) offers an extensive collection of DNS record types, each tailored to specific functions within the internet’s architecture. Currently, there are over 60 standardized DNS record types, which highlights the system’s complexity and adaptability to various networking needs.

Among these record types are the fundamental A and AAAA records, which respectively map domain names to IPv4 and IPv6 addresses, enabling the routing of internet traffic. MX records handle mail server information, directing emails to the appropriate destination, while CNAME records help aliasing one domain name to another.

Beyond these basics, there is a large number of specialized DNS record types designed to cater to specific requirements. TXT records store text data, serving purposes like domain verification and SPF (Sender Policy Framework) for email authentication. PTR records enable reverse DNS lookups, aiding in network diagnostics and security measures.

Moreover, DNSSEC (Domain Name System Security Extensions) has introduced additional record types which strengthen DNS security. These include DNSKEY records for cryptographic keys and RRSIG records for digital signatures, ensuring the authenticity and integrity of DNS data.

As technology advances, new record types may emerge to address challenges and requirements in internet communication and security. Despite this evolution, the core DNS record types remain vital components of the internet’s infrastructure, supporting its functionality and reliability.

DNS Monitoring explained

DNS Monitoring gives you the ability to manage and examine the performance of a DNS server. The main goal is to assist you with detecting server-side and client-side DNS issues. In addition, it guarantees the health of DNS servers by sending a DNS request. You are able to choose different query types depending on the DNS record you want to check, for example, A, AAAA, MX, NS, PTR, or CNAME. Then you specify a required expected response that is compared to the actually received response.

DNS Monitoring has a very important role in your network Monitoring service. Moreover, it ensures the safety and proper connection between the end-users and the website or service that they want to use. It is extremely useful when it comes to the fast detection of unpleasant issues or for recognizing potential security breaches. Additionally, it is helpful for stopping some popular malicious attacks. Thanks to the regular checks, you can effortlessly detect unexpected issues or localize DNS outages. As a result, you can prevent a large negative impact on your website or on the safety of your users that want to reach your services by detecting and resolving the problem fast.

Why is DNS Monitoring important?

The Domain Name System (DNS) is an essential part of the Internet. Yet, it was not designed with security in mind. For that reason, cybercriminals have developed ways to take advantage of its vulnerabilities. Therefore, DNS monitoring is vital for helping you protect your online presence and catch issues before they become significant problems. DNS monitoring gives you the ability to recognize several different DNS errors. The majority of them result from malicious attempts and could be a significant threat to your security. On the other hand, there are also communication flow interruptions. They compromise the functionality of your domain’s DNS resolution process and lower the traffic toward your site.

Configuration Errors

DNS Monitoring can detect errors like incorrect IP addresses and assure that outages are not prolonged. The less time your website or service is down, the less your traffic flow is interrupted. That way, you can maintain and increase your uptime, and every user that wants to reach your website (or service) will have that opportunity without any difficulties.

A configuration error can stop users from reaching your website and make it seem like their internet is not acting correctly. This could drive traffic away from your domain and meddle with your business.

DNS Spoofing (DNS poisoning)

DNS Spoofing, also commonly known as DNS poisoning, is a popular cyber threat that cybercriminals use. Recursive DNS servers hold the hostname data with all related DNS records for a particular amount of time (depending on the TTL). That way, they operate more efficiently because they do not repeat the resolution process for the same IP address. However, it also leads to vulnerabilities.

Cybercriminals insert fraudulent data into the DNS cache on the server, like fake IP addresses. Commonly, that is achieved due to viruses and malware. As a result, the users’ requests are directed to a malicious phishing website, which looks similar to the original one. There they type their sensitive information, such as passwords, credit card details, etc. A lot of people do not even notice that they have been directed to malicious pages. No one wants to put its clients at risk of phishing schemes. Additionally, compromising user information can seriously impact your business.

DDoS and DoS Attacks

Distributed Denial of Service (DDoS) and Denial of Service (DoS) attacks are massive cyber threats that are able to bring down your server. They involve large amounts of fake traffic with the main goal of overcoming your resources and making your website or service unavailable for regular users. It is important to mention that the earlier the attack is detected, the more quickly it can be handled. Therefore, it is best to stop it before the DNS records on the server become weaponized by the cybercriminals.

DNS Tunneling

DNS Tunneling is another cyber threat that attackers commonly use. Typically, DNS servers handle a massive amount of traffic, and there are no security measures regarding the exchanged data packets. DNS Monitoring can help detect tunneling and serve to prevent any further data from being exchanged. This is an essential addition to your existing security measures.

DNS outage

DNS outage does not allow your users to connect and reach your website or service. It is possible to last just several minutes, but it could continue up to several hours or even days. So you can probably imagine how seriously it can affect your business and services. With DNS Monitoring, you can easily find and understand where the issue is coming from and quickly fix it.

How does it work?

You can find DNS monitoring as a part of ClouDNS Monitoring service. It works by regularly checking if the DNS server responds to all DNS queries. With such type of check, you can initiate DNS queries for a desired hostname and query type – A (for IPv4), AAAA (for IPv6), MX, NS, PTR, or CNAME. There are two scenarios that follow once you set your expected response.

• The check is marked UP, when the received response is equal to the required expected one.
• The check is marked DOWN, when the received response is not equal to the required expected one.

The DNS monitoring check validates the conditions of DNS servers by sending a DNS request and comparing the received response with the expected one.

You can also take a look at our article about DNS monitoring Checks!

Why do you need it?

DNS monitoring is necessary because DNS performance is essential to your network, servers, and applications. Thanks to the DNS servers, your website or service works effectively and efficiently, yet they should be monitored for vulnerabilities. In case you neglect their adequate supervision, you may compromise both the security of your business and your clients.

With the ClouDNS Monitoring service, you can keep an eye on your servers and quickly detect any issues. As you know, timing is crucial, so the fast resolving of the issues is going to guarantee the integrity of your servers. So, as a result, everything should continue operating smoothly.

Benefits of DNS monitoring

DNS monitoring is a critical component of any organization’s network management strategy. By monitoring DNS traffic, organizations can proactively identify and address issues before they escalate. Here are some of the main benefits of the implementation of DNS monitoring:

• Improved Server Availability

It can help improve server availability by identifying and resolving issues that can cause downtime or service disruptions. For example, DNS servers can be vulnerable to hardware or software failures, network connectivity issues, and cyber attacks, which can affect the availability of websites and other online services. DNS monitoring services can detect and alert tech teams of problems before they escalate, allowing them to take proactive measures to resolve them.

• Improved DNS Server Troubleshooting

DNS monitoring can help improve DNS server troubleshooting by providing visibility into the DNS infrastructure and the flow of DNS queries. Tech teams can use DNS monitoring tools to identify blockages, misconfigurations, and other issues affecting the performance of the DNS server. The information helps them troubleshoot and resolve issues more quickly, minimizing downtime and service disruptions.

• Faster Detection of Outages

DNS monitoring can be useful for detecting outages faster by providing real-time visibility into the DNS infrastructure. It can alert tech teams about issues, such as DNS server failures or network connectivity problems, as soon as they occur. That way, IT teams can quickly identify the root cause of the problem and take action to restore services.

Monitoring Plan

Comparison with other monitoring techniques

DNS monitoring is a specialized approach focusing on the health and security of the Domain Name System, which is crucial for translating domain names into IP addresses. While DNS monitoring is vital, it’s one part of a broader network monitoring strategy that includes other techniques such as network performance monitoring, application monitoring, and security information and event management (SIEM). Here’s how DNS monitoring compares with other monitoring techniques:

• Network Performance Monitoring (NPM): NPM tools focus on the performance and availability of networks and network components (like routers and switches). While NPM can identify network congestion and hardware failures that indirectly affect DNS services, DNS monitoring directly assesses DNS health, ensuring that domain name resolution processes are working as expected.
• Application Monitoring: This technique focuses on the performance and availability of specific applications. It can help identify issues within an application that may impact user experience but doesn’t directly monitor DNS processes. DNS monitoring complements application monitoring by ensuring that users can reach the applications in the first place.

Security Information and Event Management (SIEM): SIEM systems collect and analyze aggregated log data from various sources to detect and respond to security incidents. While SIEM can identify security breaches that may indirectly affect DNS services, DNS monitoring provides specific insights into DNS-related security threats, such as DNS spoofing or tunneling attacks.

Conclusion

So, now you know what DNS Monitoring is and why it is so important for your security. First, there are different criminal attempts that could be prevented when you keep an eye on your servers. Additionally, it is beneficial for simplifying the process of finding and fixing network issues. Finally, it helps you prepare and not be surprised in such situations.
