I just tried it, and it took ages responding. The other site, responded near instantly. Do you have your own webspace, somewhere external from your LAN? Does it run Apache, or some other webserver where you can run commands, and have the instructions for doing so? You could run your own script to do the same thing (tell you your IP address). (See the end of this message for examples.) As to why there's different answers, there's any number of reasons. Proxies and NAT devices between you and them, being the first things that springs to mind. But, in general, there's two addresses (fairly) easily discovered from the remote end - the address of the computer that you're browser runs on (may be a LAN address), and your external IP address. Things can get confusing if the thing querying names resolves IP addresses. It may find the IP, resolve the name, then find the IP for the name. There may be more than one IP associated... An example script for Apache, a one-line page saved as address.shtml: <!--#echo var="REMOTE_ADDR" --> When requested via any HTTP agent (browser, wget, etc): wget http://example.com/address.shtml Returns just the remote IP address, on a single line, and nothing else, as the page. NB: You must be allows to run SSI (server side includes) on your webserver. You must write your page in a manner that the server expects (typically, using the .shtml suffix). The Apache manual doesn't list all of the variables that can be returned, it only lists the extra ones it adds to the CGI environment variables from ye olde NCSA web server. The NCSA ones can be seen here: http://hoohoo.ncsa.illinois.edu/cgi/env.html -- [tim@localhost ~]$ uname -r 2.6.27.25-78.2.56.fc9.i686 Don't send private replies to my address, the mailbox is ignored.
