If a local area network is connected, the ip address is the ip of the local connection on the computer. If you want to check your computer's ip address, first open your computer's browser, enter the IP in the search input box, and click Search to see your IP address. Or you can click the Windows icon, then enter CMD in the dialog box and press Enter. After entering the command window, enter ipconfig/all and press enter to see the ip details of the whole computer. The default port is 7777. If you are connected to an external network, just tell the other party the IP of your external network.
