I've looked at a lot of websites and the ports are either outdated or don't show how to find it. I know how to get into the cmd thing and all that, but I cannot find my port for the life of me. Is it always the same thing or randomized?
As I stated in my answer on your other (related) question, if you truly mean LAN worlds, you do not need to know this information. LAN worlds automatically configure this for you. Your port is shown directly next to the local IP address:
Anything behind a
: in an address specifies a port number.
