A "Minecraft" IP refers to the Internet Protocol address of a specific "Minecraft" server. Although "Minecraft" can be played in single-player mode, many multiplayer servers exist to allow multiple players to log in and play together in one large persistent world.
To find IP addresses for public "Minecraft" servers, users can consult online server lists. These lists give details on the connection address for the server as well as the rules and the game version information. When setting up a new private "Minecraft" server, the server administrator can share his own public IP address, as assigned by the Internet provider, with other players.
