Thanks for your kind replies.

Actually, what I wanted to do was to be able to tell if two ore more IPs coming from the same user belong to the same IP range (not sure what the technical name is). That information will indicate to me that at least this user is who he is (not someone from a different IP who has stolen his connection session).

Is there a way to do that? Is Net::IP the right module to use?
