Think about ip address change every time you connect to your isp, and your host name doesnt! My point is on the multi menu for connecting to games it says enter ip or host name . The box also keeps listed the ip or host name that you recently played and the name of who made the game. So if we list host names we can just click that anytime we see someone make a game. much easier then typing in ip address every other day. maybe i am just lazy but sounds good to me.
