3-6-1-1 DNS Server
Short for Domain Name System (or Service or Server), an Internet service that
translates domain names into IP addresses. Because domain names are alphabetic, they're
easier to remember. The Internet however, is really based on IP addresses. Every time you
use a domain name, therefore, a DNS service must translate 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 is, in fact, its own network. If one DNS server doesn't know how to
translate a particular domain name, it asks another one, and so on, until the correct IP
address is returned.
