If you have a /24 you can directly get delegation for the reverse on
that block of IPs. If you have a smaller block you'll have to get your
ISP to set up some pointers saying "Go over here if you want to resolve
these IPs". For example:
guin:jafo$ host 220.127.116.11
18.104.22.168.IN-ADDR.ARPA is a nickname for 2.tummy.150.17.216.IN-ADDR.ARPA
2.tummy.150.17.216.IN-ADDR.ARPA domain name pointer cantsleep.linsomniac.com
Our up-stream has set it up so that requests for reverse on our block get
mapped to the "fake" domain "tummy.150.17.216.in-addr.arpa", which they
actually pull from our DNS server.
So, you can end up handling all your DNS needs, effectively. However,
you have to have an ISP that will cooperate with this. These days that
should be most of them.
It is not enough to have a good mind. The main thing is to use it well.
