SUMMARY
This article compares and contrasts Domain Name System (DNS) Zones and
Domains.
MORE INFORMATION
Domain name servers store information about part of the domain name space
called a zone. The name server is authoritative for a particular zone. A
single name server can be authoritative for many zones.
Understanding the difference between a zone and a domain is sometimes
confusing. A zone is simply a portion of a domain. For example, the
Domain Microsoft.com may contain all of the data for Microsoft.com,
Marketing.microsoft.com and Development.microsoft.com. However, the zone
Microsoft.com contains only information for Microsoft.com and references to
the authoritative name servers for the subdomains.
The zone Microsoft.com can contain the data for subdomains of Microsoft.com
if they have not been delegated to another server. For example,
Marketing.microsoft.com may manage its own delegated zone.
Development.microsoft.com may be managed by the parent, Microsoft.com.
If there are no subdomains, then the zone and domain are essentially the
same. In this case the zone contains all data for the domain.
