1.      Most != All even in IPv4 (ran into this in a few hotels with some
                prominent MMORPG login sites)

2.      512/16 = 32, 512 / 28 = 18 (the 19th record will TRUNC).

        So, you get just over half the number of records to fit within
        the same space.

I would say that my statement that you are much more likely to
encounter TRUNC results and need a TCP query with IPv6 stands.

It also matches my experience.
