: Look up a monitoring site like HotMC or Minecraft Server List to find a server address (e.g., play.example.com ).

: Go to Play > Servers tab. You can join "Featured Servers" directly or scroll down to Add Server to enter a custom IP and port (default is 19132).

To play on existing multiplayer worlds, you do not "download" a server file; instead, you connect to an IP address within the game.
