Hmm. One way to throw the question into stark relief is to ask:
Is '10/8' *equal to* '10.0.0.0/32', in the sense that unique indexes
and operations like SELECT DISTINCT should consider them identical?
Does your answer differ depending on whether you assume the values
are of CIDR or INET type?
Once we have decided if they are equal or not, we can certainly manage
to come up with a sort ordering for the cases that are not equal.
