We do not have a zone for external addresses -- Forward/Reverse at all.

So, what is needed is to populate that zone with external resources? Does that mean, one A record per website, or can I get away with something more generic... ? And if so, what else is needed?
You guys may be better off sending me to a DNS FAQ/Howto, although I do appreciate answers tailored to my brand of ignorance
