Use Dynamic DNS Without a Long Hostname

Posted Sun Oct 23 @ 05:46:44 PM PDT 2011

My DIR-655 router comes with a cool feature that allows you to sync up your current IP address with a dynamic DNS provider like dyndns.com. Because my ISP (Comcast) can change my IP at any time, I can always use my dynamic DNS address to reach my computer on the internet.

The first thing you need to do is create an account at dyndns.org, and get a hostname setup, and pointing to your IP. Then you plug that information into your router like so (on my router, it is under Tools > Dynamic DNS):

The only problem is that you have to use a long hostname since all the short ones are taken.

To fix that, I created a CNAME record on one of my domains with the hostname me.example.com aliased to myhostname.dyndns.org. So if you have a short domain name, you can have a short dynamic DNS hostname too.
