[bitfolk] Secondary Reverse DNS

I'm currently toying with the idea of asking Andy to delegate the reverse lookup for my IP addresses to my name server rather than bothering him when I want to change them. I've been Googling to see what the zone file I'd need to create for this would look like and could only find resources on creating a zone for for an entire class C network, what would the zone file look like? (please either answer or point me to a resource I couldn't find) -- Robert Gauld http://www.robertgauld.co.uk
