Domain Name System (DNS) is a database system that translates a computer's fully qualified
domain name into an IP address. Networked computers use IP addresses to locate and connect to
each other, but IP addresses can be difficult for people to remember. For example, on the web, it's
much easier to remember the domain name www.amazon.com than it is to remember its
corresponding IP address (207.171.166.48). Each organization that maintains a computer network
will have at least one server handling DNS queries. That server, called a name server, will hold a
list of all the IP addresses within its network, plus a cache of IP addresses for recently accessed
computers outside the network.
