Domain Name System
The 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
domain name databases and their corresponding IP addresses.
To add a DNS server and specify the active DNS server:
1
Click System > IP Addressing > Domain Name System in the tree view
to display the
Domain Name System: Summary page.
Figure 9-24. Domain Name System: Summary
The list of previously-defined DNS servers is displayed.
2 To enable mapping of host names into IP addresses through a DNS server,
select
DNS Status .
3 To activate one of the currently-defined DNS servers, enable Active Server .
