Dynamic DNS – what does it mean?
Dynamic DNS is another name for Dynamic Domain Name System(DDNS). It’s a great way to update your name server automatically and on a regular basis. It changes IP addresses, as well as their corresponding A (IPv4) and AAAA (IPv6) records, whenever they change. It saves you the time and effort of manually doing this process.
Internet Service Providers (ISPs) are constantly changing customers’ IP addresses. As a result, they face significant difficulty ensuring that they do not run out. Every device that connects to its network needs a unique IP address.
How does it work?
Principally, to implement DDNS, you’ll need to choose a DNS Hosting provider. Then, once you find it, you can run their software on the host computer or router. This software connects to the DDNS service provider when the IP addresses provided by the ISP are modified. As a result, the Dynamic DNS provider updates the A or AAAA record to reflect the changes, resulting in near-instant changes.
Furthermore, networks that employ static IP addresses are incompatible with a DDNS service. This is due to the fact that the domain name does not need to be requested again after the IP address is provided the first time. The explanation is simple: static IP addresses never change.
Why should you use Dynamic DNS?
The primary argument is simple: using Dynamic DNS to make something available online is less expensive. Yes, you may get static IP addresses for each of your connected devices, but how much will it cost? IPv4 addresses are becoming increasingly costly and hard to find. But, if you’re curious, it will still be much less expensive than paying for static IP addresses, even if you pay for a DNS service plan.
The other key consideration is that it is relatively simple to operate. For example, setting up DDNS on your router is similar to setting up anything else. You go to the settings and fill in the necessary information. On the other hand, creating an account on a DNS site and, afterward, creating a new host is likewise relatively quick and straightforward.
So, in summary, Dynamic DNS provides a cost-effective and user-friendly alternative to purchased static IP addresses.
