Dynamic DNS

Use our Dynamic DNS service if you would like to host your own web server, mail server, ftp server, etc. but you do not have a static ip. This is great to keep a pointer back to your home PC so you can access important information from anywhere. You can use our free update client or one of the available third-party update clients to keep your hostname always pointing to your IP address, anytime even is your ISP changes it. No more fumbling to find that piece of paper where you wrote down your IP address, or e-mailing all your friends every time it changes. Just tell them to domain name instead! You are also not limited to how many dynamic domains you can use as you can use it with ever A record you create.


To assist you with configuring your hostname we've created this flash tutorial to show you how easy it is to create.
