What you describe - authorities used by people off your network to resolve A records with IP addresses outside your 
network - is not what Joe was describing.  What the recursive name server your end users queried to resolve names, the 
IP address in their desktop's control panel, outside your network?

I can see a small ISP using its upstream's recursive name server.  But to the rest of the world, most small ISPs look 
like a part of their upstream's network.
