geez. all this trouble....install djbdns and you will forget about its 
existence. Things just work.

In bind, you need to define a zone and create the 
stuff similar to the

200   IN PTR

With djbdns, you can just install and run walldns and 
forward/split-horizon queries for to the walldns 
instance if you don't need names. or you install tinydns if you want names.
