This is a plugin for Minecraft Bukkit servers.
Players can have multiple accounts or have friends who share or login together. This is useful for admins to know. For example if one account has admin or creative privileges, they might be tempted to share among themselves.
This plugin reports the related player accounts as they login (to players with permission). It also has a cool feature of reporting the geographical location they are from (if that information is available at the time).
Give players (or admin groups) "joe.iptracker.notify" permission to receive notifications in game. There is an in-game "/ipt" command also you can use to check version or lookup a player specifically. To grant access to that command give permission "joe.iptracker" also.
