Yes! In todays classless networking, this is exactly what you have to do, and
i also configured such a DNS thing, which was checked by RIPE afterwards and
found to be okay. The trick is: Just create a zone for every IP address. It
is evil with a /25 network, /27 is also lots of files, but this is the only
way to just resolve single addresses.
So create a zone entry in named.conf for the zone
and for this "zone", create a zone table containing
18.104.22.168.in-addr.arpa. IN PTR blah.junk.com.
(ow something like this...)
Looks strange, but is the official way to implement it.
