Specifying a Subnet Broadcast Address
You configure a broadcast address for a subnet differently from the way you
configure a broadcast address for a network. When you extend the network
portion of the IP address to create a subnet address, you automatically take away
from the host portion of the address. To configure a subnet broadcast, you take the
subnet mask for that subnet and invert it. For example, if the IP address of the
subnet is 10.4.2.3, and the mask is 255.255.0.0, then the subnet broadcast address
is either 10.4.255.255 or 10.4.0.0.
