What is dynamic DNS?


Dynamic DNS technology allows you to give your home network PC or server a permanent address on the Internet. Internet service providers change your IP address on a regular basis, but with dynamic DNS you can keep your domain name pointed to the current IP address of your home server or other devices.

How does Dynamic DNS Technology work?


  • Your PC is connected to the internet and runs Dynu Client. Dynu Client keeps track of your computers IP address and reports it to Dynu DNS servers.
  • When someone requests 'yourname.dynu.com', Dynu DNS servers redirect them to your computer just like InterNIC DNS servers redirect requests to 'yourname.com'.
  • Now any user on the internet can connect to your PC instantly by requesting 'yourname.dynu.com'.
