2.0.0.2.ip6.arpa is also broken in all colors.

soa @ns.apnic.net. for ip6.arpa. has serial: 2004071900
soa @ns.icann.org. for ip6.arpa. has serial: 2004071900

   === 3 were also authoritatve for 2.0.0.2.ip6.arpa.
   === 0 were non-authoritative for 2.0.0.2.ip6.arpa.
ERROR: Found 2 diff sets of NS records

WARNING: ns-sec.ripe.net. claims to be authoritative for

   == but no NS record at parent zone

==> so although the three remaining NS for ip6.arpa have the same SOA
    serial, they obviously have a different view on the NS RRset for
    2.0.0.2.ip6.arpa... and all are authoritative for 2.0.0.2.ip6.arpa.

Now looking at the NS RRset ns-sec.ripe.net returns for 2.0.0.2.ip6.arpa:

  == ns-apnic.6to4.nro.net. ns-arin.6to4.nro.net. ns-lacnic.6to4.nro.net.
  == ns-ripe.6to4.nro.net.

soa @ns-apnic.6to4.nro.net. for 2.0.0.2.ip6.arpa. serial: 2004072901
dig @ns-arin.6to4.nro.net. for SOA of 2.0.0.2.ip6.arpa. failed
soa @ns-lacnic.6to4.nro.net. for 2.0.0.2.ip6.arpa. serial: 2004072901
soa @ns-ripe.6to4.nro.net. for 2.0.0.2.ip6.arpa. serial: 2004072901

==> ns-arin.6to4.nro.net == tinnie.arin.net, so we have the same IPv6
    reachability problem again

What a mess all over... why do ns.apnic.net and ns.icann.org return
NXDOMAIN when queried for the NS RRset for 2.0.0.2.ip6.arpa, but
ns-sec.ripe.net returning one? It looks like the whole 2.0.0.2.ip6.arpa
is missing in the ip6.arpa zone, and ns-sec.ripe.net is only by chance
carrying the 2.0.0.2.ip6.arpa zone, thus returning the NS RRset.

I wonder where's the right place to report such global (multi-RIR/org)
DNS problems to, if not v6ops. I see no "global IPv6 operations" list,
can anyone enlighten me?
