3.7.1.1 DNS Server

Choose DNS Server in the left pane. The page shown in the following figure appears.

Domain name system (DNS) is an Internet service that translates the domain name into IP address. Because the

domain name is alphabetic, it is easier to remember. The Internet, however, is based on IP addresses. Every time

you use a domain name, a DNS service translates the name into the corresponding IP address. For example, the

domain name www.example.com might translate to 198.105.232.4. The DNS system has its own network. If one

DNS server does not know how to translate a particular domain name, it asks another one, and so on, until the

correct IP address is returned.
