Dynamic DNS: Why is it important?

Have you ever heard about Dynamic DNS and how important it is? If not, no worries. You are in the right place. Why? Because today’s article focuses on the significance of the Dynamic DNS, its purpose, and how it operates. So, let’s start exploring it.

Dynamic DNS purpose

Dynamic DNS (DDNS) automatically updates and modifies a host’s IP address. As a result, visitors will be able to access your website even if the IP address changes due to it.

DDNS is a simple solution that allows you to connect to your various hosted services when your ISP changes your IP address (IPv4 or IPv6). For example, let’s imagine you have a web hosting server, a database server, and a mail server, or you use your home network to connect your CCTV cameras to the Internet using DDNS.

Changing IP addresses makes it easier for ISPs to manage their networks. As a result, they only rent them to their customers for a limited period. Instead, they delegate this responsibility to a DHCP server for this purpose. As a result, when the time period expires, the clients are assigned a new IP address.

The way it works

DDNS works by mapping custom host names to specific network devices/resources. For example, let’s imagine you want to be able to view a security camera mounted on your front door from anywhere on the planet. Of course, you’ll need an IP address to achieve this, which will allow you to connect to the camera via the Internet.

If your ISP changes the IP address, the old IP address you used to access the camera will no longer operate.

When you use a DDNS service to map a fixed, custom hostname to a resource, you can be confident that you’ll always have access to it, even if the underlying IP address changes.

Why do you need to benefit from Dynamic DNS?

The key motivation is straightforward: making something available online via Dynamic DNS is less expensive. Yes, you can receive static IP addresses for each connected device, but at what cost? IPv4 addresses are becoming more costly and challenging to come by. Even if you pay for a DNS service plan, it will still be significantly less expensive than paying for static IP addresses if you’re curious.

Another critical factor to consider is that it is quite straightforward to use. Setting up DDNS on your router, for example, is comparable to setting up anything else. You go to the settings and fill in the required data. Creating an account on a DNS service and then creating a new host is, on the other hand, a reasonably simple and quick process.

In conclusion, Dynamic DNS is a more cost-effective and user-friendly option than purchasing static IP addresses.


DDNS is a fantastic service. Should you take advantage of it? It will save you money and function perfectly in most circumstances, so take it into consideration. Additionally, it may even be the sole reasonable answer to a problem in some situations. For example, suppose you wish to deliver services or connect and operate many devices, such as CCTV cameras, over the Internet. So yes, check it out. Good luck!
