I've been banned for trying to play a game with my brother

[Brutishcrab51]

So, I was trying to play an online game with my brother (living in the same house as me) on Dawn of the Tiberium Age, and another friend of mine, and we were 'G-lined'. I'm not sure what this means as a phrase, did the server itself think we were a DDoS attack? Are we not able to use the same IP to play a game? How do I go about getting our IP ban removed?
