Answer : script of website that discovers your ip address

to display a user's IP it's simply:

$_SERVER["REMOTE_ADDR"];

Browser/OS info you typically can get from $_SERVER['HTTP_USER_AGENT']; too... but there are many bits of code to extract the info from it in a nice way such as: http://apptools.com/phptools/browser/source.php

go get location have a look at http://www.phptutorial.info/iptocountry/the_script.html for a nice(ish) way to do it without a mysql table.

ISP - will probably need to get from some webservice...
