Yep, as decided about three years ago. But now, ip6.arpa delegation
for 3ffe::/16 is there, so there's no good reason anymore to support
the ip6.int domain.

Ideally, glibc should do:

- nibble format in ip6.arpa
if that doesn't succeed:
- nibble format in ip6.int

no bitstring queries!

Current FC1 glibc does:

- bitstring format in ip6.arpa
- nibble format in ip6.int

It would be REALLY cool to have a glibc upgrade also for FC1, as more
and more ISPs are dropping their ip6.int and bitstring format queries
don't work... so IPv6 reverse DNS resolving is quickly going down the
drain for FC1.
