DNS Properties
The Domain Name System (DNS) is a database of Internet hostnames with their
corresponding IP addresses distributed over designated DNS servers. It enables
network users to refer to hosts by name, rather than by IP addresses, which are
harder to remember. Use this window to enable the use of DNS servers for
hostname-to-address translation.
