DNS classless address delegation setup

Question

I'm hoping someone can help me. I'm trying to setup my Leopard server to handle DNS reverse IP lookups on our half class C address range. I think I have everything entered correctly. By default the Server Admin GUI wants to auto setup the full class C range .1 - .255. We only have .128 - .255. Our ISP has set us up as the SOA for both our zones AND the IP range 128/25.xxx.xxx.xxx.in-addr.arpa.
I've tried to create a zone file with this name (128/25.xxx.xxx.xxx.in-addr.arpa.) which of course give me issues with the "/" so I've changed the zone file name to 128-25.xxx...
And everything looks correct and no other errors but this one comes up about ignoring out of zone data:
21-Mar-2008 16:04:30.524 db.128-25.xxx.xxx.xxx.in-addr.arpa.:12: ignoring out-of-zone data (212.xxx.xxx.xxx.in-addr.arpa)
This is the only IP I care about reversing as it's our mail server.
My setup is as follows and may not be the correct approach so please correct me:
I've made an entry in publicView.conf.apple (it says not to but I get errors about using views, if I make an entry directly in named.conf)
zone "128/25.xxx.xxx.xxx.in-addr.arpa" {
type master;
file "db.128-25.xxx.xxx.xxx.in-addr.arpa.";
allow-transfer {any;};
allow-update {none;};
My Zone file looks like:
$TTL 10800
128/25.xxx.xxx.xxx.in-addr.arpa. IN SOA dns.domain.net. apurvis.domain.net. (
2008032100 ;Serial
86400 ;Refresh
3600 ;Retry
604800 ;Expire
345600 ;Negative caching TTL
128/25.xxx.xxx.xxx.in-addr.arpa. IN NS dns.domain.net.
212.xxx.xxx.xxx.in-addr.arpa. IN PTR mail.domain.net.
My ISP has setup their system to pull zone data from my DNS server. This is working fine for my domain names (zones) but not for the reverse ip.
Please help, and Thank you!

You need to match the zone name your ISP has delegated to you.
We have one customer with the same setup working (Tiger server) but we have to do it manually not through the GUI.
The named.conf and zone file should probably look something like:
zone "128-25.xxx.xxx.xxx.in-addr.arpa" {
type master;
file "db.128-25.xxx.xxx.xxx.in-addr.arpa.";
allow-transfer {any;};
allow-update {none;};
$TTL 10800
128-25.xxx.xxx.xxx.in-addr.arpa. IN SOA dns.domain.net. apurvis.domain.net. (
2008032100 ;Serial
86400 ;Refresh
3600 ;Retry
604800 ;Expire
345600 ;Negative caching TTL
128-25.xxx.xxx.xxx.in-addr.arpa. IN NS dns.domain.net.
128-25.xxx.xxx.xxx.in-addr.arpa. IN NS <ISP slave/secondary-dns name>.
???.128-25.xxx.xxx.xxx.in-addr.arpa. IN PTR dns.domain.net.
212.128-25.xxx.xxx.xxx.in-addr.arpa. IN PTR mail.domain.net.
I have used www.dnsreport.com / www.dnsstuff.com reverse lookup to see the DNS traversal ("backtrace"), but they now restrict usage a bit or you can pay to use their services.
Using that might reveal the correct name of the zone (if you don't get it working with the above name).
