From a network engineering point of view the inet type is utterly
bogus. I'm not aware of data of that type being needed or used in
any real application. Given that, the complexity that it causes
simply by existing seems too high a cost.

I suspect that the right thing to do is to kill the inet type
entirely, and replace it with a special case of cidr. (And possibly
then to kill cidr and replace it with something that can be indexed
more effectively.)

For a replacement type, how important is it that it be completely
compatible with the existing inet/cidr types? Is anyone actually using
inet types with a non-cidr mask?
