is this really true? i think not. it depends on your subnetting. the
broadcast address is the one with all host bits set.

i use binary notation to make it clear:

netmask:   11111111.11111111.11111111.11110000
network:   00001101.11001100.01010101.00110000
ip:        00001101.11001100.01010101.00110001
broadcast: 00001101.11001100.01010101.00111111

any address ending with 255 is a broadcast address in class C networks
(netmask: XXX.XXX.XXX.0).

i hope i didn't mess something up. :-)

regards ...
