It does not help that two of these three nameservers are actually
the exact same thing. Counting v4 and v6 there's four distinct
addresses. Weirdly enough I sometimes get an answer from one of
them, sometimes from two of them, but never from all four. Even
sometimes an answer comes from the v4 address of a host but not its
v6 address or vice versa. Which is most odd as presumably it's the
same bind9 process listening on both addresses.

Cheers,
Andy
