As far as I known
That was true when only class A, B and C networks did exists. The actual
definition is, that the broadcast address is always the highest address of the
network. So if you hav a Network 10.0.0.1/255.255.254.0, the address
10.0.0.255 is a normal ip-Adress of this network, and has to pass all routers.
The Broadcast adress of this network is ONLY 10.0.1.255.
