DNS in Small Networks
Domain Name System (DNS) is a system for naming computers
and network services that maps those names to network addresses and organizes
them into a hierarchy of domains. DNS naming is used on TCP/IP networks, such
as the Internet and most corporate networks, to locate computers and services
by using user-friendly names. When a user enters the DNS name of a computer in
an application, DNS can look up the name and provide other information that is
associated with the computer, such as its IP address or services that it
provides for the network. This process is called name resolution.
