Quoting Michael Paoli (Michael.Paoli@cal.berkeley.edu):
If you could please, and would be willing, could you cover DNS slave services for BALUG, notably these zones: e.9.1.0.5.0.f.1.0.7.4.0.1.0.0.2.ip6.arpa balug.org master(s) (all for each of the above): 198.144.194.238 2001:470:1f04:19e::2
FYI, ns1.linuxmafia.com is repeatedly logging this:
Feb 20 17:50:45 linuxmafia named[17291]: zone e.9.1.0.5.0.f.1.0.7.4.0.1.0.0.2.ip6.arpa/IN: refresh: failure trying master 2001:470:1f04:19e::2#53 (source ::#0): operation canceled
I'm unsure why the AXFR/IXFR to the IPv6 address fails, and currently lack the time and patience to pursue that matter. For now, I'm going to disable that master IP on my BIND9 conffile.
Before I do that, Michael, would you like to any some checking on the _master_ nameserver end? The most probable explanation is some deficiency in IPv6 support on ns1.linuxmafia.com, and that would be my default assumption.
FYI, both zones are affected:
