Managing Bans

Minecraft, and consequently Sponge, has simple ban management to prevent unwanted users from joining your server.

The /ban <name> [reason] command is a native Minecraft server function that bans player name. The complete list of banned players is available using the command /banlist players

It is also possible to ban any connections from a given IP address using /banip <address|name> [reason]. The complete list of banned IP addresses is available using the command /banlist ips

A ban can be reversed using the command /pardon <name> or /pardon <ip-address>

More information on Bans can be found at the Minecraft Wiki.
