Plugin AntiMulti

AntiMulti Minecraft Server Plugin

AntiMulti is an older Bukkit plugin designed to limit alternate accounts connecting from the same IP address. It helps Minecraft server administrators reduce account abuse, repeated joins, and some forms of session theft by comparing player names and IP addresses.

Its configurable protection distinguishes regular players from administrators, supports permission based exemptions, and can allow trusted users or families to share an address when necessary. Limits, registration checks, administrator protection, and whitelist behavior can be adjusted. AntiMulti is not a complete proxy solution, but it provides a practical layer of access control for legacy servers, with BoxToPlay making server management straightforward.
