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.
