3.6.1.1. DNS Server
Choose DNS Server, 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.
