I'm having a problem getting ipv6 reverse delegation to work and I'm hoping someone can tell me what I'm missing, as it seems to me this should be pretty straightforward:
$ host
4.3.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.1.0.1.8.7.6.f.7.0.6.2.ip6.arpa
8.8.8.8
Using domain server:
Name: 8.8.8.8
Address: 8.8.8.8#53
Aliases:
Host
4.3.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.1.0.1.8.7.6.f.7.0.6.2.ip6.arpa
not found: 3(NXDOMAIN)
The authoritative nameserver is serving it up:
$ host -t ptr
4.3.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.1.0.1.8.7.6.f.7.0.6.2.ip6.arpa
ns1.rdrop.com
Using domain server:
Name: ns1.rdrop.com
Address: 2607:f678:1010::53#53
Aliases:
4.3.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.1.0.1.8.7.6.f.7.0.6.2.ip6.arpa
domain name pointer agora.rdrop.com.
The parent authoritative nameserver (for 2607:f678::/32) is serving the
correct delegation NS records:
$ host -t ns 0.1.0.1.8.7.6.f.7.0.6.2.ip6.arpa ns1.peak.org
Using domain server:
Name: ns1.peak.org
Address: 2607:f678::53#53
Aliases:
0.1.0.1.8.7.6.f.7.0.6.2.ip6.arpa name server ns1.rdrop.com.
0.1.0.1.8.7.6.f.7.0.6.2.ip6.arpa name server ns2.rdrop.com.
Even for the intermediate levels, though I don't think that should
actually be necessary once the delegation gets to the top level
(8.7.6.f.7.0.6.2.ip6.arpa):
$ host -t ns 1.0.1.8.7.6.f.7.0.6.2.ip6.arpa ns1.peak.org

$ host -t ns 0.1.8.7.6.f.7.0.6.2.ip6.arpa ns1.peak.org
