Reverse Configuration Problem?

i'm a little confused.... why do you have a master zone configured for
this reverse zone?

unless you own the entire class c, you should have your ISP add a PTR
record to change:
this....

;235.126.180.64.in-addr.arpa.   IN      PTR

;; ANSWER SECTION:
235.126.180.64.in-addr.arpa. 60 IN      PTR    
s64-180-126-235.bc.hsia.telus.net.

;; AUTHORITY SECTION:
126.180.64.in-addr.arpa. 86383  IN      NS      helium.bc.tac.net.
126.180.64.in-addr.arpa. 86383  IN      NS      neon.bc.tac.net.

to this.....

;; ANSWER SECTION:
235.126.180.64.in-addr.arpa. 60 IN      PTR     ns.oddjobsbc.com.

;; AUTHORITY SECTION:
126.180.64.in-addr.arpa. 86383  IN      NS      helium.bc.tac.net.
126.180.64.in-addr.arpa. 86383  IN      NS      neon.bc.tac.net.

unless you're authoritative for this class c you can't create this PTR
record, nor should you try to.  If you have like 10 or more IP addresses
you might convince your ISP to delegate to you using the CNAME hack but
most likely they won't.

your nameserver is responding just fine, and thinks it's authoritative
for that IP address.  however it's not :>
