the ip6.int entry times out, no servers reached.
the ip6.arpa entry fails immediately w/ NXDOMAIN.
the delegation for 3ffe:37:: is
7.3.e.f.f.3.ip6.int. in ns gemini.psc.edu.
in ns charon.psc.edu.
.....
these servers are -NOT- responding to queries.
perhaps you should contact Michael Lambert for more detail.
