The broadcast address depends entirely on the subnetmask used. An address ending in .255 can be valid for instance if you have subnetmask that is less than 24 bits. This is not something you would find in most networks. But I have seen at least one network where they utilized switches to flatten the entire network. Interesting result was the 3b2 systems arp caches started churning due to all the arp broadcasts. Kind of funny looking back on it now.
