The Domain Name System (DNS) translates domain names understood by you and me into IP addresses which are understood by computers and networking equipment the world over. It is a hierachical naming system built on the largest distributed database for computers, services or pretty anything connected to the Internet or private network. An easy to understand analogy that is used often to explain the Domain Name System is that it serves as the "phone book" for the Internet by translating human friendly computer hostnames into IP addresses such as 65.174.185.62. This happens every time you use a domain name, whether you are viewing websites, sending email, or using any Internet related service. Essentially DNS is involved with everything on the web and is the glue that holds the Internet together. Without DNS the Internet simply would not work.
