[Pdns-users] Reverse lookups

[bdushok at luzerne.edu]

Norbert/Bert,

        Thanks.  I can't believe I did that :)

        There still seems to be a problem, but I don't think it's with 
Power DNS.  The output (with the CORRECT dig parameters LOL) is:

;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 60524
;; flags: qr aa rd; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 0

;; QUESTION SECTION:
;38.108.224.199.in-addr.arpa.   IN      PTR

;; ANSWER SECTION:
38.108.224.199.in-addr.arpa. 3600 IN    PTR     www.luzerne.edu.

;; Query time: 1 msec



        Notice the output when I do the same thing against my ISPs DNS:



[root at tomcat root]# dig @199.224.86.20 -x 199.224.108.38

; <<>> DiG 9.2.0 <<>> @199.224.86.20 -x 199.224.108.38
;; global options:  printcmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: SERVFAIL, id: 5331
;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 0

;; QUESTION SECTION:
;38.108.224.199.in-addr.arpa.   IN      PTR

;; Query time: 15 msec
;; SERVER: 199.224.86.20#53(199.224.86.20)
;; WHEN: Thu Sep  4 12:40:19 2003
;; MSG SIZE  rcvd: 45

        This seems to the be result when I perform the query against 
anything but my own DNS servers. 

        My ISP and other DNS servers can do forward lookups and show 
recently made changes (results not being displayed from cache). 

        Bob
