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.
