This comment on my recent rant on not needing to know your own IP address made me think about my own experiences in online gaming. True, it's a while ago - in the mid-nineties, when I was very keen on playing Bolo by Stuart Cheshire – one of the finest games around.
Even back then, I never needed to know my own IP address to play a game. Some tracker application would happily register that with some server. And that was in 1995 or so, you should've thought technology has evolved since. In fact, I think it has – but programmers became worse and even more lazy. Thus, users of their software may need to know their IP addresses. It remains silly, though.
