If your behind a proxy or have a complicated network setup, this will fail. For most DSL/Cable modem customers this simple solution will work fine. These services are going to get the IP address of the last packet sent from the network. If you have more than one router, this will be the last router (NAT device) in your setup. It should work for most simple cases though. There are also some other web servers out there that offer this functionality. Just Google on external or outside IP and see if any of the other sites show any differences. > I would consider using the dynamic dns services - such as no-ip - and > use a perl script that updates then ping your dns name.

I would bet they may have the same problems with proxy servers and such but it would be worth a try. Good Luck, Tom
