    Hey guys, I have my own domain and my own BIND9 DNS server. I wanted to check if ns1.joinpgn.com is the authoritative DNS server for joinpgn.com. How do I do that?

    Here's from a local machine in my house.

    Code:
    [root@hp-a500n ~]# dig joinpgn.com SOA

; <<>> DiG 9.3.4-P1 <<>> joinpgn.com SOA
;; global options:  printcmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 35261
;; flags: qr rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 0

;; QUESTION SECTION:
;joinpgn.com.                   IN      SOA

;; ANSWER SECTION:
joinpgn.com.            38400   IN      SOA     ns1.joinpgn.com. administrator.joinpgn.com. 1229546904 10800 3600 604800 38400

    How come when I do the remote dig lookups it says AUTHORITY 0?
