Dynamic Domain Name Resolution Configuration Guide
Domain Name System (DNS) is a distributed database used by TCP/IP applications
to translate domain names into corresponding IP addresses. With DNS, you can
use easy-to-remember domain names in some applications and let the DNS server
translate them into correct IP addresses.
