Okay, let me see if I have this straight. Originally, I've never had a 
168.192.in-addr.arpa here. I just ran a 254.168.192.in-addr.arpa. I need to 
add:

a) Create 192.168 in-addr:

; File /etc/dns/primary/zone.192.168.0
$TTL 86400
@       IN SOA  flame.fireclick.com.    root.flame.fireclick.com. (
                         2001051500                      ; serial
                         10800                           ; refresh
                         3600                            ; retry
                         604800                          ; expiry
                         86400 )                         ; default_ttl (1d)
;
         IN      NS      flame.fireclick.com.
         IN      NS      ns1.fireclick.net.
         IN      NS      ns2.fireclick.net.
;
; Corporate Domains
;
254     IN      NS      flame.fireclick.com.
17      IN      NS      flame.fireclick.com.
;
; Eng Domains
;
11      IN      NS      scorch.eng.fireclick.com.
;
; QA Domains
;
0       IN      NS      qans.qa.fireclick.com.

b) Create reference in named.conf:

         zone "24/0.168.192.in-addr.arpa" {
                 type master;
                 file "primary/zone.192.168.0";
                 allow-query {
                         any;
                 };
                 allow-transfer {
                         localhost;
                         fireclick-xfer;
                 };
         };

(this is in the "in" view for 9.1.2, which I'm upgrading to now).

Do I understand this correctly? Then, as we add more sub-domains, I simply 
add the pointer in the 168.192.in-addr.arpa zone file?

One final question. What if I want the primary DNS (flame.fireclick.com) to 
be a secondary for these sub-domains? What HAS been the problem is that 
when I set up flame as the secondary for the ENG and QA domains, I get a 
not-authoritative error message when the reverse trys to transfer.

Thanks for the assistance.
