DNS
Domain name system (DNS) is an Internet service that translates
domain names into IP addresses. Because domain names are
alphabetic, they are easier to remember. The Internet, however, is
actually based on IP addresses. Each time you use a domain name,
a DNS service must translate 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 system is, in fact, 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.
