OK. There are basically 3 ways DNS queries can be answered – authoritative, recursive, and cache. I assume then he means recursive and cache? As opposed to something like a DNS proxy in a router which just queries another resolver but caches the answers?

Actually, with so much Internet content now being either dynamic HTML or streaming, I wouldn’t think caching would be worth it, unless you are talking about something like a Netflix OpenConnect appliance. Maybe you can cache software updates, I’m not sure about that.
