3.5.1 DNS
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, DNS translates the name into the corresponding IP address. For example, the domain name
www.example.com might be translated to 198.105.232.4. The DNS 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.
Choose Service > DNS. The DNS page that is displayed contains DNS and DDNS.
