What Is A Domain Name?
A domain name is used to identify a particular place (IP address
number) on a particular computer (server) where the files of a web/Internet
site (URL) are located.
Each site on the Internet has a unique number, very similar to
a phone number. This number is called the Internet Protocol (IP)
number or address. For example, the IP address for businessnames.ca
is 209.227.206.63. This identifies the computer and the specific
place on the computer where the site is located.
However, all these numbers are very long and difficult to remember.
Thus, early on in Internet history, these numbers were given pseudonyms
called domain names that were easier to remember and type. These
domain names are translated or "mapped" onto the numerical IP address.
This is done by domain name servers, individual computers that are
spread throughout the Internet.
