[Pdns-users] NS answer inconsistency between implementations for delegated zone

Hi Peter,

Thank you for your response.

I have been testing with 2.9.22.6, but I get the same results with 
Powerdns 3.0.

But are you sure you're doing a NS query ? Because an A query results
in having the RRs in AUTHORITY, but not an NS query:

$  drill ns info.example.com
;; ->>HEADER<<- opcode: QUERY, rcode: NOERROR, id: 56881
;; flags: qr rd ; QUERY: 1, ANSWER: 2, AUTHORITY: 0, ADDITIONAL: 0
;; QUESTION SECTION:
;; info.example.com.    IN      NS

;; ANSWER SECTION:
info.example.com.       7200    IN      NS      ns1.other.net.
info.example.com.       7200    IN      NS      ns2.other.net.
