[[File:DNS_Zone.png|link=//upload.wikimedia.org/wikipedia/commons/thumb/6/6a/DNS_Zone.png/300px-DNS_Zone.png|thumb|300x300px|Illustration of [[Domain Name System|DNS]] zone for ''en.wiki.org'']] A '''DNS zone''' is a specific portion of the DNS namespace in the [[Domain Name System]] (DNS). It is managed by a specific organization or administrator. A DNS zone allows for more control of the DNS components, such as [[Name server|authoritative nameserver]]. The DNS is broken up into many different zones. They are distinctly managed areas in its namespace. However, a DNS zone can contain several [[Subdomain|subdomains]]. Multiple DNS zones can exist on the same server. A DNS zone is implemented in the configuration system of a [[domain name server]]. Historically, it is defined in the [[zone file]], an operating system [[text file]] that starts with the special DNS record type ''Start of Authority'' (SOA) and contains all records for the resources described within the zone.{{Reflist}} {{tech-stub}} [[Category:Domain Name System]]
