I was playing Project Cars 2 with my brother, who lives with me, and I got him to download the CC app because its awesome. We are both hearing each other's CCs and spotters. We are connected to the same LAN and I'm guessing that CC uses a broadcast address?

Im just looking for an explanation as to why this is happening to see if I can come up with a work around, because if this is how CC works, then in order for it to work properly in my situation may require a major rewrite of code, and I am not asking for that as it is unreasonable for a rare circumstance. Any insight would be appreciated!
