Tenhle problem je "vyresen": A6 je snad minulosti, pouzivejte AAAA.

http://www1.ietf.org/mail-archive/ietf-announce/Current/msg19416.html

"The (rough) consensus of the community is that the A6, Binary Labels
and DNAME DNS extensions should not be widely deployed for use with
IPv6 at this time, and that IPv6 should continue to use the same basic
mechanisms as IPv4 uses today."

Problem je v tom, ze nejnovejsi resolvery se vetsinou ptaji na adresy v
zone ip6.arpa ale v tyhle zone neni vubec zaznam pro adresy 6bone
(3ffe::/16), protoze nejake RFC sit 6bone neuznava jako RIR. Takze pulka
IPv6 internetu vlastne neni resolvovatelna. Az se tenhle problem vyresi,
tak asi dostane ip6.arpa prednost.
