Explanation of Dynamic DNS
Another name for Dynamic DNS is Dynamic Domain Name System (DDNS). It’s a fantastic approach to automatically and frequently update your name server. When IP addresses change, it also updates the A (IPv4) and AAAA (IPv6) records that go with them. You don’t have to spend the time and energy conducting this process manually.
The IP addresses of their clients are frequently changed by Internet service providers (ISPs). They consequently have a lot of trouble ensuring they don’t run out. Each device that connects to the network requires an individual IP address.
The way it functions
You won’t need to worry about checking and updating your IP address after signing up for the DDNS service. But first, a little more explanation of the procedure.
Through the Internet, your company provides a service. Your server or servers are thus available. You must take a few actions to make the service accessible to outside users. A Network Address Translation (NAT) router is required for internal business networks to connect to the Internet. Your server(s) will receive an IP address thanks to NAT.
Port forwarding will be necessary, together with an IP address (IPex) and an external port (Portex). Done! The service is currently accessible to outside users online. IPex changes will now either cause a problem or not, depending on whether you purchase DDNS service.
DDNS software is installed on your network once you’ve signed up for a provider’s DDNS service. The IPex is added to the DDNS information, and the NAT must be set up to update the IPex as needed and notify the DNS server of the change.
The only thing NAT will require you to do is add your DDNS account and password. For your peace of mind, they will collaborate and communicate constantly.
Dynamic DNS pros
As discussed in the previous section, Dynamic DNS is a convenient service. So, let’s look at the main benefits of using it.
- It is simple and straightforward to configure and use.
- DDNS changes IP addresses automatically and checks for updates. That is a significant benefit for you or your administrator. It allows for more time to be spent on other critical tasks.
- Because it provides automation, the possibility of human error is reduced.
- With some DNS hosting providers, it is either very cheap or even free. Furthermore, you can obtain a static IP address and eliminate the risk of downtime caused by IP address changes. Nevertheless, owning a specific IP address exclusively is a costly alternative.
Conclusion
Just now, you learned what Dynamic DNS is and what its key benefits are compared to static IP numbers for your server. It might even be the only rational answer to a problem in some circumstances. For example, let’s say you want to use CCTV cameras as an example of a device you want to connect to the Internet to give services.
Do you want to utilize it? Consider using it since, for the most part, it will function well and save you money. The only issue is that Dynamic DNS only operates well as a DNS provider. So consider carefully which DNS service to select if you can’t afford downtime.
