Which DNS term describes the portion of the namespace managed by a single server?

Explanation:
In DNS, the name space is organized like a tree, and the portion of that name space for which a particular DNS server is authoritative is a zone. A zone is defined by a zone file that contains the resource records for the domain names within that boundary, and DNS servers can delegate subzones to other servers using NS records, which marks the administrative boundary of the zone. The other terms describe different ideas: a domain is a node or label in the tree, the root is the very top of the tree, and the tree is the entire hierarchical structure. So the part managed by a single server is correctly called a zone.
