AFAIR, the inet/cidr types consider IPv4 to be an independent set of
values that sort in front of all IPv6 values.  The notion that IPv4
might be embedded in some part of the IPv6 space is not something that
that code is aware of.  If it did try to do that, you'd have
'::ffff:192.0.2.124' comparing as equal to '192.0.2.124', which would
be okay for some purposes but not all.
