I absolutely agree, except for network(), which should return cidr.
(after all, this is the network).

As I mentioned in another email, should inet datatype really care whether
host part is all-ones or all-zeros and reject that? It would make sense to
me (10.0.0.0/8::inet is not a valid address, but 10.0.0.0/8::cidr is), but
it would break some people's scripts...

I'm talking here from a perspective of a network provider with P
knowledge...I'm sure Marc can chime in here...
