Plugin IP-Check

IP Check, multi account detection for Minecraft servers

IP Check is a Bukkit plugin designed to help staff identify players using multiple accounts on a Minecraft server. It records the accounts associated with each IP address, supports searches by player name, and can track connections across different IPs. Administrators can define account limits, enable Secure Mode, and receive alerts when a player exceeds the permitted number of accounts.

For moderation, the plugin can link related accounts, apply bans to every account connected to an IP, and remove those restrictions with a single command. It stores data through MySQL or SQLite and has no external dependencies. At BoxToPlay, we recommend it for older Bukkit server environments focused on practical alt account checks.
