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.
