A network of proprietary servers set up by Blizzard Entertainment and accessable via their games or reverse-engineered chat-only clients. The idea was to give all Blizzard customers a freely accessable central place to find fellow players; however, the system is plagued by lag, netsplits, and worst of all, mass quantities of lamers. Because of this, several players of Blizzard's games have abandoned b.net in favor of Kali, the FSGS network, or private servers that use the reverse-engineered FSGS daemon.
