I can't find the external IP for Minecraft Java multiplayer
I don't know where to find the external IP I've heard about for Minecraft Java multiplayer, because I have friends I want to play with that live half a state away and whenever I open to LAN it only shows the port number in the chat.
“Open to LAN” only allows people on the same network to play with you. If you want to play with your friends in another state, you’ll need to set up a server. If you don’t want to go through all the work associated with this, you can use a free hosting service such as aternos.org.
