Game Guide Help

Helo tripleaaa here i was wondering if i could be using the same internet for two people with this game. My brother plays this game also and seems to never play because we cant be on the same internet on the game i thought. I was wondering if any admin or guide knew if we can get on the same internet but on differnt computers. And if it can`t be done could you look at my and his account and know we are on same internet but different computers so i wouldnt perhps get banned if we cant i wont do it.
