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.
