NoDupeIP
What It Does
This plugin binds the player's username to his IP. This can be very useful when griefers are trying to connect with ALTs. For best protection, use MaxBans with "DnsBL" enabled in the configuration (it prevents known proxies to join the server).Commands & Permissions
At the moment, there are 2 commands:/nodupeip - Administrator commands that reload the plugin (will implement config editing in later versions). Permission: ipbind.admin
/ip [username] - Allows you to see a player's IP address. Permission: ipbind.ip
Commandless permissions:
ipbind.iponjoin - Allows you to see someone else's IP when they join.
