|This feature is exclusive to Java Edition.|
- The port to host on, between 0 and 65535. If not specified, a random port above 1024 is chosen.
This command appears in the singleplayer cheats. Cannot be used on a multiplayer server.
Fails if the world is already published to LAN, or if the port could not be bound (e.g. a reserved port, or already in use by another application).
On success, opens your singleplayer game for LAN friends to join.
