Broadcasting is limited to a specific subnet, and must use User Datagram Protocol (UDP.) For Internet Protocol version 4, you can broadcast to your local subnet by sending a packet to 255.255.255.255; or you can use the directed broadcast address, which is the network portion of an Internet Protocol (IP) address with all bits set in the host portion. For example, if your IP address is 192.168.1.40 (a Class C address, with a netmask of 255.255.255.0 -- the network portion is the first three octets, and the host portion is the last octet), your directed broadcast address is 192.168.1.255.
Setting this property on a Transmission Control Protocol (TCP) socket will have no effect.
