Lets just say that your main server network is 192.168.0.0/16.
The sub domain you want to have delegated is 192.168.100.0/24
You therefore have a file 192.168.rev on your main domain dns server.
with
$ORIGIN 192.in-addr.arpa.
168 IN SOA dns.maindomain.com.au. hostmaster.maindomain.com.au (
1 7200 1200 86400 7200 )
IN dns.maindomain.com.au.
IN otherdns.maindomain.com.au.
and this
$ORIGIN 168.192.in-addr.arpa.
1.1 IN PTR dns.maindomain.com.au
etc
or this
$ORIGIN 1.168.192.in-addr.arpa.
1 IN PTR dns.maindomain.com.au.
etc
then to answer your question.
the glue record to delegate some of it away.
$ORIGIN 168.192.in-addr.arpa.
100 IN SOA dns.subdomain.maindomain.com.au.
hostmaster.maindomain.com.au (
1 7200 1200 86400 7200 )
IN dns.subdomain.maindomain.com.au.
IN anyotherdns.somedomain.com.au.
If you can't delegate a whole c class in the reverse to your subdomain,
things get a bit messy.
eg: say I want to delegate 192.168.100.32/28
Then in the main dns I have this.
$ORIGIN 192.in-addr.arpa.
168 IN SOA dns.maindomain.com.au. hostmaster.maindomain.com.au (
1 7200 1200 86400 7200 )
IN dns.maindomain.com.au.
IN otherdns.maindomain.com.au.
$ORIGIN 100.168.192.in-addr.arpa.
32 IN CNAME 32.32/28.100.168.192.in-addr.arpa.
33 IN CNAME 33.32/28.100.168.192.in-addr.arpa.
34 IN CNAME 34.32/28.100.168.192.in-addr.arpa.
35 IN CNAME 35.32/28.100.168.192.in-addr.arpa.
36 IN CNAME 36.32/28.100.168.192.in-addr.arpa.
37 IN CNAME 37.32/28.100.168.192.in-addr.arpa.
38 IN CNAME 38.32/28.100.168.192.in-addr.arpa.
39 IN CNAME 39.32/28.100.168.192.in-addr.arpa.
40 IN CNAME 40.32/28.100.168.192.in-addr.arpa.
41 IN CNAME 41.32/28.100.168.192.in-addr.arpa.
42 IN CNAME 42.32/28.100.168.192.in-addr.arpa.
43 IN CNAME 43.32/28.100.168.192.in-addr.arpa.
44 IN CNAME 44.32/28.100.168.192.in-addr.arpa.
45 IN CNAME 45.32/28.100.168.192.in-addr.arpa.
46 IN CNAME 46.32/28.100.168.192.in-addr.arpa.
47 IN CNAME 47.32/28.100.168.192.in-addr.arpa.
32/28 IN SOA dns.subdomain.maindomain.com.au.
hostmaster.maindomain.com.au
1 7200 1200 86400 7200 )
IN dns.subdomain.maindomain.com.au.
IN anyotherdns.somedomain.com.au.
On the subdomain server
$ORIGIN 32/28.100.168.192.in-addr.arpa.
32 IN PTR host1.subdomain.maindomain.com.au.
33 IN PTR host2.subdomain.maindomain.com.au.
I hope I have made all this clear enough.
regards,
Dave

Subject: [SLUG] off topic
I know that this is off topic, but I would appreciate an answer very
much:
I have created a subdomain with it's own DNS server in my domain. What
should I add in my domain DNS server to delegate the reverse zone of my
subdomain
