In DNS, which element is reserved for a specific server?

Explanation:
In DNS, the zone represents the portion of the domain name space for which a particular DNS server is authoritative. It’s the administrative boundary that defines who holds and serves the data for that slice of names. A zone is defined by a zone file on the server, and the server answers queries for every name within that zone. Because the zone is the container of authoritative data for that part of the namespace, it’s effectively “reserved” for the server or group of servers that administers it, with zone transfers to any secondary servers to keep data in sync. The broader domain is just the namespace, not the specific administrative boundary the server controls; a record is an individual entry inside a zone, and realm isn’t a DNS term.
