One way you can do it, if you did want to go by IPs (which can be a pain).. I did one site where the owner wanted to track all IP by users, so I made it so you can see each users signup ip, last activity ip, etc.. basically if the user did anything on the site with a new ip, it would be tracked.. (or do a subset), and I had it so you can view a certain IP, and see all of the users who had some kind of activity with that ip..
It can be helpful for finding users with multiple accounts
