I've tried commands like /net_ip and /showip (something like that) and all they say is "localhost". I'll do a check on the game start-up that you've suggested. Many thanks!

Edit: Tried to host, but nowhere in the console was my IP displayed.

Edit: /net_ip does show the IP address, except that my router causes it to display "localhost". Perhaps the game would say otherwise on my laptop... Next thing to do is to get my friend to try joining my game.
