What is the concept (purpose) of Dynamic DNS?

You must first grasp DNS in order to comprehend what Dynamic DNS (DDNS) is. It is a mechanism that associates a domain name, such as squadrainformatica.com, with an IP address (

The same idea is applied by Dynamic DNS but to a WAN IP that changes over time or is “dynamic.” Since having a fixed WAN IP address that never changes is expensive, the majority of household broadband plans do not contain a static WAN IP.

In other words, even if you write down or memorize your current WAN IP address, you generally shouldn’t rely on it to dial your home phone. This is because when you do, that address might have changed to someone else’s home network.

To solve this problem, we use DDNS. It links your current WAN IP address, whatever it may be at any given moment, with a reliable domain name of your choice.

As a result, you don’t even need to know your home network’s IP address to access it using that label (domain name) from anywhere in the world.

Why is it necessary for you to gain from Dynamic DNS?

The main driver is simple: using Dynamic DNS to make something available online is less expensive. For each connected device, you can get static IP addresses, but at what cost? IPv4 addresses become more costly and hard to find. If you’re curious, even purchasing a DNS service plan will still be less expensive than purchasing static IP numbers.

One other vital factor to consider is how simple it is to use. For example, configuring DDNS on your router is similar to configuring anything else. First, you go to the settings and enter the necessary information. On the other hand, creating a DNS account and then a new host is a relatively simple and quick process.

In conclusion, Dynamic DNS is a less expensive and more user-friendly alternative to purchasing static IP addresses.

What exactly is a Dynamic DNS update?

The IP address associated with a DNS record is changed during Dynamic DNS updating. The changes occur automatically and in real-time, and the user is unaware of them.

This type of modification would have been carried out manually, but the use of an update. The client now allows for quick, lightweight upgrades that take place in the background. The host computers can request an address from a DHCP server or set one up automatically, after which they can inform the DNS server. In order for DDNS client computers to update their resource records whenever changes are made, DNS updates can be configured through the server. If this feature isn’t required or is posing a security risk, it can also be turned off.


In conclusion, Dynamic DNS (DDNS) is a service that enables you to provide your network or server with an internet address that is always active. When a supplier of the internet (ISP) changes an IP address, it instantly updates DNS records. This is particularly helpful if you host servers through your connection so that anyone attempting to connect to you can do so by using your domain name rather than your Dynamic IP address, which changes periodically.
