reverse OK for all IPs except one

[Joe Kattner]

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
