What is a DNS zone?
Rating:
A DNS zone is a contiguous portion of the DNS tree that is administered as a single separate entity by a DNS name server. It is a unit that stores authoritative information about the DNS name space. A DNS zone can consist of a single domain or a domain with sub-domains. DNS zones are the main units of replication in DNS. Windows 2003 supports three DNS zone types: primary, secondary, and stub.
