you don't install reverse DNS, it's just another zone file, not something in its own right. So like your main zone file you have one for the PTR records like this... http://www.zytrax.com/books/dns/ch6/reverse-map.html Of course you need the subnet to be registered to your DNS services for this, so whilst you can go buy daveshotpants.com and make it point it's DNS services at you, you can't do the same for the PTR records, as that would require the whole of the /24 subnet of public space that uses (as I understand it), which would contain all sorts of other sites and uses for that internet address space. For your own internal private networks, sure though, go nuts.
