This article was originally written when Monolith (ml.org) offerred free dynamic dns facilities. Unfortunately, Monolith is no longer. So most of this page became irrelevent.

See the end of this page for other organisations.

What is dynamic DNS?

I've written a bit about DNS already. But most DNS entries assume the IP is static and will not change on a regular basis. This is fine for machines that are permanently connected to the Internet and have a static IP address. But most of us have dynamic IP addresses which change every time we log on. That makes it necessary to update the DNS entries on a regular basis.

Client software

The primary method of updating your DNS records is using a browser. That is not very convenient if you dial up frequently and get a new IP every time. There is something better; a dynamic-DNS client

Other organisations that provide this service include:

DNS Wizard
Dynamic Host Information System - they have shut down but source code is available
Dark Technologies
The Free Dynamic DOMAIN project (uses software from http://gnudip.cheapnet.net)
Microtech DNS Servers

More service providers 22 January 2001
