I think it's useful when you have an ancient network where the broadcast
address uses 0-bits, rather than 1-bits - i.e., ip 192.168.1.1 with a
netmask of 192.168.1.0 and a broadcast address of 192.168.1.0 *not*
192.168.1.255. It's archaic, but allowed. Don't know if stuff <10 years
old will choke on that or not.
