92	SOA record in DNS server	kchen	ecprice	"Zones are supposed to have an SOA record at the top of each zone.  When the DNS server is queried for an SOA record, it claims there are 0 answers, but then returns one in the authority section:

kchen@scyther:~$ dig -t soa xvm.mit.edu @sipb-xen-dev.mit.edu

; <<>> DiG 9.3.4 <<>> -t soa xvm.mit.edu @sipb-xen-dev.mit.edu
; (1 server found)
;; global options:  printcmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 61583
;; flags: qr rd; QUERY: 1, ANSWER: 0, AUTHORITY: 1, ADDITIONAL: 0

;; QUESTION SECTION:
;xvm.mit.edu.                   IN      SOA

;; AUTHORITY SECTION:
xvm.mit.edu.            3600    IN      SOA     sipb-xen-dev.mit.edu. sipb-xen.mit.edu. 1 3600 900 3600000 21600

This dig should result in the SOA record being placed in the answer section.  Also, the SOA serial number should increase each time the zone information is updated.  If there's some mechanism for tracking the last time the database was updated, that could be used as the SOA serial number."	defect	closed	minor		dns		fixed
