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.
