BIND can serve data in one of two ways -- as an authoritative
server, or as a caching server. Either way, you've got some sort of
database that you're operating from.
Your caching resolvers are presumably going to serve data from a
lot of domains other than the ones that you own yourself. What's
wrong with having them cache the data from your own servers? If
there is a problem with caching the data from your own servers, then
why not set the TTLs really low?
