[Pdns-users] IPv6-only support and AAAA only on NS's seem to not work correctly

[Jeroen Massar]

According to http://wiki.powerdns.com/cgi-bin/trac.fcgi/ticket/18,
pdns-recursor should have full IPv6 support. But...

$ dig @::1 pseudohacker.se ns
;; ->>HEADER<<- opcode: QUERY, status: SERVFAIL, id: 13675
;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 0

;; QUESTION SECTION:

$ rec_control dump-cache /tmp/the-cache
ns0.pseudohacker.se. 86387 IN AAAA 2001:16d8:ff00:15a::2
ns1.pseudohacker.se. 86387 IN AAAA 2001:16d8:ff56::53

$ dig @::1 ns0.pseudohacker.se aaaa
ns0.pseudohacker.se.    86349   IN      AAAA    2001:16d8:ff00:15a::2

$ dig @::1 www.pseudohacker.se aaaa
;; ->>HEADER<<- opcode: QUERY, status: SERVFAIL, id: 27468

;; QUESTION SECTION:

;; ANSWER SECTION:
www.pseudohacker.se.    21600   IN      AAAA    2001:16d8:ff00:15a::2

;; AUTHORITY SECTION:
pseudohacker.se.        21600   IN      NS      ns0.pseudohacker.se.
pseudohacker.se.        21600   IN      NS      ns1.pseudohacker.se.

;; ADDITIONAL SECTION:
ns0.pseudohacker.se.    21600   IN      AAAA    2001:16d8:ff00:15a::2
ns1.pseudohacker.se.    21600   IN      AAAA    2001:16d8:ff56::53

I thus guess that pdns_recursor doesn't really like the AAAA-only NS's?
Can you confirm, test and fix? :)

3.1.4-2 pdns_recursor package on debian btw.

Greets,
 Jeroen
