Assume that example.com and foo.example.com have different zone files which in-turn have different ns entries day ns1 and ns2. So if I query for the A record of foo.example.com will it be answered by ns2? If so can I assume that the .com tld server has entries for both example.com and foo.example.com?
So, what are the practical application of zones? I can think of load balancing DNS queries as one.
