Domain Name System
Domain Name System (DNS) converts user-defined domain names into IP addresses. Each time a
domain name is assigned, the DNS service translates the name into a numeric IP address. For example,
www.ipexample.com is translated into 192.87.56.2. DNS servers maintain databases of domain names
and their corresponding IP addresses. The Domain Name System contains the following windows:
• Defining DNS Server
• Host Mapping
Defining DNS Server
The DNS Servers Page contains fields for enabling and activating specific DNS servers. To enable a
DNS client:
1. Click System > System Management > Domain Name System > DNS Servers. The DNS Servers
Page opens:
DNS Servers Page
