This is described briefly in the presentation at
http://www.ws.afnog.org/afnog2004/t1/dns/dns3-01-slides.pdf
(page 7 and 8)

Basically, you create master zone files for
64.100.212.in-addr.arpa
65.101.212.in-addr.arpa
...
95.100.212.in-addr.arpa

containing the SOA and NS records as usual.

You'll need at least two authoritative servers (one master, one or more
slaves) for each zone, and they should be on different networks as per
RFC2182. This is just the same as a normal forward DNS zone.

Then you contact the RIPE robot and request delegation. Once this is
working, then you add entries in your zone files like
1	IN	PTR	foo.bar.com.
2	IN	PTR	baz.bar.com.
etc. for the actual hostnames.
