I'm trying to find a cool link for you...
here's one..but automatically traces YOUR ip #. The one I'm looking for lets you post an IP number for free...it shows a map, and traces all the routes say from an email you have received.

Very very cool! You could use it to track your hubby's emails when he is away to make sure he is where he says he is. Not that my hubby would do that but I know people whose hubbies would!!!
I am about to go to bed but will peruse this and may become an internet detective. Doesn't that sound fun?
