What is the purpose of Dynamic DNS?

Have you ever heard about Dynamic DNS? It is an absolutely incredible service. Why? Because it lets you connect to your gadgets over the Internet using a simple domain name. In our article, we will take a detailed look at it, how it functions and why it is so beneficial.

Dynamic DNS – what does it mean? 

Dynamic DNS (DDNS) stands for Dynamic Domain Name System. It’s a great way to update your name server automatically and regularly. Whenever they change, it changes IP addresses and their related A (IPv4) and AAAA (IPv6) records. It saves you the time and effort of manually doing this process.

An amazing Dynamic DNS service that is worth your attention!

Client IP addresses are continually changing at Internet service providers (ISPs). As a result, they face a significant problem in managing them so that they do not run out. Every device that connects to its network needs its IP address.

Perhaps you are unaffected by these frequent IP changes as a typical home Internet user. Businesses, on the other hand, are a different matter. If a company provides a service -or numerous services- over the Internet, such IP address changes will almost certainly harm its servers. In addition, every update increases the possibility that users requesting the service will be denied access because they are using an old, invalid IP address.

How does it work?

Dynamic DNS continuously monitors IP addresses for changes. When a change occurs, the DDNS automatically updates the new IP address.

Consider sharing service from a server that is connected to the Internet. It must also be connected to the internal network, and it will use a network address translation (NAT) router to communicate with the Internet. This NAT router assigns an internal IP address to the server. Then it must enable its external availability via port forwarding and obtaining a Portex (external port) and an Ipex (internal port) (external IP address). Your service will already be visible at this stage. Users will have easy access to it over the Internet.

Why is it advantageous?

The following are some of the benefits that DDNS can provide:

• Dynamic DNS is a low-cost alternative. There are both commercial and free DDNS providers available. It is, nevertheless, less expensive than purchasing static IP addresses for your company’s equipment.
