Bah I prolly wasn't clear enough, I confused myself

, what I'm talking about is when you use user.php and search for a user. You find and click and view his IP's then click the link to find other users that have identical IP addresses. Well I have one user that I want to remove several IP's from that way when other admins search and view the IP's of that user or try finding people that match him, because his IP's will no longer be in the database, it won't match.
