This sort of service should be given by the ISP, since the ISP is the one allocating the IP number, and at least I know them as an entity. If the ISP is not giving me a static IP then I should at least be able to determine my IP from the ISP rather than having to go to another site. > All they do is turn around the REMOTE_ADDR variable in your browser > request.

No-one would use such a service when services such as > whatismyip.com work fine. Well, they would. For the reasons I gave above.

Log into your router/modem and it will tell you your ISP-assigned IP. Not rocket science. >> All they do is turn around the REMOTE_ADDR variable in your browser >> request.
