You can't really "identify someone" from the IP address-- but if it's a stable IP address assigned to a named host, you can get the name of the host. We use a local tool to do that on certain occasions. A colleague who knows about this stuff noted the "gethostbyaddr" function in Perl and C--but also noted a freeware Windows utility that packages this function. It's true freeware (no payment expected), it's tiny, and it seems to work just fine. The name of the utility is "ghost" and you can download it from: http://www.webattack.com/freeware/network/fwip.shtml (scroll down to "ghost") Disclaimers: 1. I'm no expert on this kind of stuff (I'm barely even a novice) 2. This is a personal response with help from my friends. RLG does not recommend this software or have anything to do with its creation. In other words, don't blame me (or RLG) if it does something wrong.
