DNS Domain Name System
The DNS maps domain names into IP addresses. DNS information is
distributed hierarchically throughout the Internet among computers
called DNS servers. For example,
www.yahoo.com is the domain name
associated with IP address 216.115.108.243. When you start to access a
web site, a DNS server looks up the requested domain name to find its
corresponding IP address. If the DNS server cannot find the IP
address, it communicates with higher-level DNS servers to determine
the IP address. See
