v1.8.4 - 4/26/2007
Fixed an issue some were having with Windows Server 2003. Also added an option to log the status messages.

v1.8.1 - 1/6/2007 - HAPPY NEW YEAR!!!
This update adds SHA1 username/password encryption support required by the updated FreeDNS API. I also fixed a cookie issue with the transfer control that I've been meaning to get to for a while. Please let me know if you run into any issues with the version.

v1.7.4 - 2/21/2006
The update last night didn't seem to work for everyone. Try this one and let me know how it goes. I changed it to use the Remote IP detection
on this server rather than the one at

v1.7.3 - 2/20/2006
Ok... someone made changes to the Remote IP detection script. This should resolve the problems that people have been having. Let me know how it goes. Seems to work fine for me.

v1.7.1 - 2/3/2006
This update was required due to some changes at Some of the expected responses were changed. I also added gzip compression support to the transfer control to even further cut down on the bandwidth required to support this service. If you've been having problems lately updating your IP this should resolve it. If not let me know and I'll fix it. :)

v1.6.2 - 12/1/2005
Happy Holidays!!!! This update takes care of some of the issues in the last release. It is now also compliant with the new update method required by Thanks to everyone that let me know about the issues in the last release. If you find any probs with this release or have any comments or suggestions for future updates let me know.

v1.5.11 - 5/3/2005
I guess it wasn't quite ready yet after all. :) I was looping through the array of domains and jumped out of the loop before I processed the last one. For those that only use 1 domain it wasn't finding anything. This update should do the trick! Sorry about that!

I know what your thinking! IT'S ABOUT TIME!!!
Sorry it's taken so long to get an update done. If you find any problems or have any suggestions for the next release, please let me know. :)
