3.7.1 DNS
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.
