What is CobianDDNS?

CobianDDNSCobianDDNS is a client used to automatically update a Dynamic DNS, which is registered on ZoneEdit. There are no plans at this moment of supporting other DDNS services, but you never know...

The program runs as a Windows Service and supports dynamic update even behind a router. CobianDDNS is a .NET application, so you need the .NET 3.5 framework to be installed for the service to work. The program will work on Windows XP or better.

The program is freeware and provided even with source code.

 

Why do you need CobianDDNS?

If you own a domain name, but your internet provider doesn't give you a static IP address, chances are big that your IP address keeps changing periodically. Your provider's  DHCP server assigns you an IP number, which will expire after some time. Then, a new address will be assigned, which may be different than the previous one.

Services line ZoneEdit allow machines with IP addresses that change to have permanent addresses on the internet. You can buy a domain name anywhere, and then use ZoneEdit's dynamic DNS solution to point that domain name to your machine. What you need to do now is to inform ZoneEdit when your IP changes and update the address, so the domain name points to the new one.

CobianDDNS does this automatically for you. The service will periodically ask your computer (or your router) for its IP address. If the address has changed, it will connect to ZoneEdit's servers and update your domain (or domains). Any changes done will be logged or send to you by e-mail.

 

Installation

Run the setup program. This will install your service, but it will not start right away. Before you start the service, you need to configure it.

Configure the program with the configuration utility. Save your changes and restart the service.
