[wplug] A little OT: Tracking down an IP address

[Ghataora, Hardeep]

You can use a network 'whois' tool to track down the ISP of a user
pretty well. From their, you'd need to contact the ISP and see what they
say, most likely, they'll say go away, most ISPs log when you're online
and what IP you were assigned for technical response issues. 

www.samspade.org has a neat little tool where you can stick an IP in and
it does stuff to it. 

There are a whole other bunch of tools that will do it too, 'whois' on
your *nix being one. 
Don't be surprised if your ISP tell you to go away.

Below is a sample.

This is a little odd, but how would I track down somebody who posted a
form that recorded their IP address?

I have the IP of the poster, and time and date of post.

The problem, for the curious, is repeated, profane and libelous posts to
a forum site I'm associated with. I really just want them to know I know
who they are - spook them a little. ;)

This might not be possible, but I figured you guys would know if it
could be done.

Thanks,

Scott
