Get familiar with Dynamic DNS

Description of Dynamic DNS

First off, Dynamic DNS, also known as DDNS, is a service that will instantly update your IP address (the A or AAAA record) if the host (device) changes it.

When your IP address’s lease ends, your ISP (Internet service provider) can change it automatically.

You can use DDNS to ensure that the device will remain accessible if you utilize it as a server. Otherwise, you won’t be able to reach the new IP address or determine it from a distance.

Without Dynamic DNS, if you are operating a monitoring server with a camera at home and you have been viewing the video from a distance, the connection will break the instant the ISP changes the IP address, and you won’t be able to see anything.

Why choose DDNS?

It offers several highly practical advantages:

  • Simple to use. All you need to do is to type the required information, and then you will be able to use it. 
  • Real-time notifications of IP changes are sent to the DNS server.
  • Accessing your server or website continuously. Users can access you simply by typing in your hostname, regardless of IP address changes.
  • It’s an affordable solution. DDNS service providers might be charged or be free. It costs less than purchasing static IPs for the devices used by your company.
  • People that use their home computer to host an app, game server, website, etc., will definitely experience the advantages of DDNS.
  • Your remote workers will have no trouble using remote access or a VPN.
  • You are installing surveillance equipment at your company. For them to function correctly, an Internet connection is required. With DDNS, they can remain reachable all the time.
