In your zone file for the class c (x.y.z), you'd create a delegation like
this in the zone file:
; For 0-127
0/25 NS some.server.
0/25 NS some.other.server.
1 CNAME 1.0/25.z.y.x.in-addr.arpa.
2 CNAME 2.0/25.z.y.x.in-addr.arpa.
...
; For 128 on...
128/25 NS some.server.
128/25 NS some.other.server.
129 CNAME 129.128/25.z.x.y.in-addr.arpa.
130 CNAME 130.128/25.z.x.y.in-addr.arpa.
...
...then the servers you delegated to have this:
named.conf:
zone "0/25.z.y.x.in-addr.arpa" {
...
...
}
...and in the zone file:
1 PTR some.host.
...
as normal.

Subject: classless ptr setup
Sent by: bind-users-bounces+johnh=primebuchholz....@lists.isc.org
I have a full /24, which I would like to separate into two /25's, and
assign each half to two of my customers. The snag is that *I* maintain
the DNS for each of these customers.
Is it possible to create the classless setup within my system so that it
starts with the /24 but can assign the two classless /25's ?
If so, I am stumped on the setup. Any help would be appreciated.
