IPCompare is CodeEx's second plugin publicly released on dev.bukkit.org. This plugin is meant to allow server owners and staff to check/compare player's ips, list every ip a user has logged in from and check if accounts have logged on from the same ip. It also limits the number of connections allowed from one ip and warns allowed players of connections from same ips. This is just a way to help stop griefers with multiple accounts.


  • Check the ip of a player on line with a simple command
  • Compare and see how many accounts use the same ip
  • List all ip addresses associated with a player's account
  • List all ip addresses that have connected to the server since the addition of the plugin
  • Get warned of duplicate accounts on login
  • Limit the number of accounts that can connect from an ip
  • Excludes ops and players with granted permission from limitations of ip or account number
  • Very lightweight

Commands and permissions:

  • /compare [player ip] - Shows you all the players in the list with the specified ip.
  • /iplist [page index] - Lists all the players in the IPCompare player list.
  • /ip [player] - Shows you the ip of the player specified if he is online.
  • /listips [player] - Lists the ips that the specified player has logged in from.
  • /warntoggle [player] - Adds or removes the player to the list of player that are warned when people login with same ip as others.
  • /purgeip [player] - Removes all entries of a player from the list.


  • ipcompare.admin - Gives permission to all commands from this plugin.
  • ipcompare.warn - Warns the player of an account logging in from an ip that is already listed.
  • ipcompare. nolimit - Exclude the player from any limitation of ips or account number.
  • ipcompare.* - Gives the player all the above permissions.


  • limit-type: - The type of account limit to use. Parameters:
  • none - (default value) Does not limit accounts per ip
  • online - Limits the number of accounts that can be online at the same time per ip
  • general - Limits the number of accounts that can join the server from one ip. Once you log in from one account, other accounts can't.
  • max-number-connection-from-ip: - The limit of accounts per ip. (disconsidered if limit-type is none) Takes in a number
  • Database: Still not implemented wont make any difference if you edit it.
  • message-language: choose the language for the kick message. options: EN - english / DE - dutch / FR - french / GE - german / IT - italian

How to install:

Download the IPCompare.zip and extract it to you plugins folder if you do not already have the plugin. If you do have the plugin add the files that are missing from the IPCompare folder and overwrite the config.yml and IPCompare.jar with the ones in the zip file.
