If that were the case, they'd be seeing the same via IPv4. And apparently,
they aren't.

This also points out the problems with *ASSUMING* you know the size of
someone's netblock. If you think "/64", then you'd be wrong. Just as
wrong as assuming all IPv4 is "/24". And on the same side of that coin
is the over-reaching "block all of Asia" blacklist. Sure, that'll kill
a heap of nonsense, but if you actually have business in Asia...

(Yes, *I* banish APNIC. "works for me", not recommended for others.)
