Open your server in the panel and click Network. The entry marked Primary is your server address, for example:
node1.penguhost.com:4123Players use exactly this in the game's multiplayer menu. For Minecraft Java: Multiplayer → Add Server → Server Address node1.penguhost.com:4123. For Bedrock: address node1.penguhost.com, port 4123. For Steam games: the Network tab shows the game port; the query port (if the game needs one) is listed in your Startup variables.
Why is there no port 25565?
Every server on a machine needs its own port, and all our Minecraft servers share the same host name. So your port is in the 4000-4500 range instead of the default. Players do not notice: they type the address once and save it.
If you want players to join with a clean address like play.myserver.com without a port, set up a domain with an SRV record.
The IP address instead of the name
node1.penguhost.com resolves to our public IP in Frankfurt. The name is the safer choice: if we ever change the IP, the name follows.
