There are two types of IP broadcast traffic. Local broadcast are packets directed to 255.255.255.255. These packets are not forwarded by any routers, and are used either for local discovery (who is directly connected to the sender), or for local peer communications (such as leader election). Directed broadcast packets are sent to the broadcast address of a specific network (determined by placing all 1's inside the host field). Directed broadcasts may be used for remote host discovery, or as a workaround for IP anycast.
