[Pdns-users] Confused about authoritativeness

[Mohamed Lrhazi]

This is a dig for a record present in my database, I anonymized the
first two octets of my IPs:

[root at pdns-dr-1 ~]# dig campus.georgetown.edu @192.168.39.40

; <<>> DiG 9.8.2rc1-RedHat-9.8.2-0.10.rc1.el6_3.3 <<>>
campus.georgetown.edu @192.168.39.40
;; global options: +cmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 37194
;; flags: qr aa rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 0

;; QUESTION SECTION:
;campus.georgetown.edu.         IN      A

;; ANSWER SECTION:
campus.georgetown.edu.  30      IN      A       192.168.19.164

This a dig for a record that is not in the db, tcpdump shows the
request was sent out to external DNS server:

[root at pdns-dr-1 ~]# dig georgetown.edu @192.168.39.40

; <<>> DiG 9.8.2rc1-RedHat-9.8.2-0.10.rc1.el6_3.3 <<>> georgetown.edu
@192.168.39.40
