On May 10, 2000, Thomas Mullaney sent me the following:

I have to do this on a couple of blocks here, the piece of named.conf
that is of interest is just:
zone "128-26.254.181.205.IN-ADDR.ARPA" {
type master;
file "zones/205.181.254.128-26";
}
and the zone file looks like (changed domain name for no good reason)
@ IN SOA domain.dom. email.domain.dom. (
124 86400 900 120000 3600 )
IN NS ns1.domain.dom.
IN NS ns2.domain.dom.
129 IN PTR name.domain.dom.
...
190 IN PTR lastname.domain.dom.
On the server with 205.181.254.0/24, the NS record looks like
128-26 IN NS ns1.domain.dom.
128-26 IN NS ns2.domain.dom.
then each address has a
129 IN CNAME 129.128-26.254.1181.205.IN-ADDR.ARPA.
line with it.
I've found AT&T at least like to use / instead of - in the rev name,
so it end up looking like 128/26.254.181.205.IN-ADDR.ARPA instead.
