You need to add a PTR for it, the A record is for forward resolution.

Subject: reverse OK for all IPs except one
Hi,
I've been fighting with my DNS for 2 hours. I can reverse lookup on
all my internal IPs except one :
Example of good query
> dig -x 192.168.0.254
; <<>> DiG 8.3 <<>> -x
;; res options: init recurs defnam dnsrch
;; got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 4
;; flags: qr aa rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 1, ADDITIONAL:
1
;; QUERY SECTION:
;; 254.0.168.192.in-addr.arpa, type = ANY, class = IN
;; ANSWER SECTION:
254.0.168.192.in-addr.arpa. 6H IN PTR ns.inerd.
;; AUTHORITY SECTION:
0.168.192.in-addr.arpa. 6H IN NS ns.inerd.
;; ADDITIONAL SECTION:
ns.inerd. 6H IN A 192.168.0.254
;; Total query time: 1 msec
;; FROM: brooklyn to SERVER: default -- 192.168.0.254
;; WHEN: Thu Jan 17 14:36:13 2002
;; MSG SIZE sent: 44 rcvd: 96
Now the only bad query :
> dig -x 192.168.0.100
; <<>> DiG 8.3 <<>> -x
;; res options: init recurs defnam dnsrch
;; got answer:
;; ->>HEADER<<- opcode: QUERY, status: NXDOMAIN, id: 4
;; flags: qr aa rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 1, ADDITIONAL:
0
;; QUERY SECTION:
;; 100.0.168.192.in-addr.arpa, type = ANY, class = IN
;; AUTHORITY SECTION:
0.168.192.in-addr.arpa. 6H IN SOA ns.inerd. admin.inerd. (
1997022709 ; serial
8H ; refresh
4H ; retry
5w6d16h ; expiry
6H ) ; minimum
;; Total query time: 1 msec
;; FROM: brooklyn to SERVER: default -- 192.168.0.254
;; WHEN: Thu Jan 17 14:37:02 2002
;; MSG SIZE sent: 44 rcvd: 104
The IP 100 is in the middle of the file and has nothing special ...
(I see the NXDOMAIN BUT I have a A record)
Could it be an alteration of the cache file ? (I've used
'service named restart' many times)
TIA
ps : could you forward to fxbois at free.fr
