Running the game on multiple computers
Until this point, we’ve been running multiple instances of our game on the same machine. But the strength of multiplayer comes from playing with multiple people over multiple machines.
In this section, we’ll start off by showing the server’s IP address on screen and then look into how we can run a debug instance on multiple computers at the same time so they can connect.

We have been using ::1 as the IP address that loops back to the same computer so that we can debug our game.
