Adding a DNS zone
A zone refers to a section of a domain for which the DNS server has the authority to perform lookups. Each zone contains records that specify how to translate the host names associated with the zone.
DNS servers can contain sub-zones and arbitrary zones. DNS zones are divided into smaller zones called sub-zones whereas, the individual zones of authority within the DNS domain are known as arbitrary zones.
To add a DNS zone:
On the administrator Home page, in the Microsoft DNS area, click add zone. The DNS add zone form is displayed.
In the zone name text box, enter a name for the DNS zone.
Click add.
The list of DNS zones displays the new zone.
