Some people have claimed that the gateway address of a
network isn't necessarily the zero address in that network.
If that's true, then you *can't* calculate the network
address from a host address and a netmask -- there isn't
enough information. Furthermore, an IPNetwork object
needs to be able to represent a network address whose
address part contains bits that aren't in the mask.
