The domain name system (DNS) enables each
machine connected on the Internet to be recognized by a domain name.
Every computer on the Internet has a unique IP (Internet protocol)
address which consists of a string of numbers. Since the IP addresses
can be difficult to remember, the DNS allows a familiar string of
letters (the "domain name") to be used instead of the IP address. So
instead of typing the IP address' arcane string of numbers you can type,
for example, "www.hostblast.net"
