A very valid and good point, that didn't pop up to me at that moment.

Though these are IPv6 reverses, hosts trying to look them up will most
likely have IPv6 enabled.  IPv6-only hosts (if they exist) will most
likely simply skip over the server and try the next one. It doesn't hurt
having it not defined though, it was just something I noticed while tracing.

Oops, no, but I'll forward the message there also. Thanks for the tip.
I actually only looked in the SOA of arin.net where bind at arin.net is
found which should be appropriate enough, I hope. Hmm, I wonder all of a
sudden why I didn't do a whois for their IP block as that contains
noc at arin.net. I'll just blame my lack of caffeine/sleep for that. (not
caused by this but simply by doing too many things at the same time)

I don't think sending it to dns-operations is 'indiscreet' especially as
there might be people who where seeing similar issues, but just couldn't
figure out yet why it was occurring. Thus see this, like my small notice
on top of a recent message to ipv6-ops at lists.cluenet.de, just as a
friendly note.

Greets,
 Jeroen
