Dns Name Resolution

Abstract

Name resolution is an important part of computer networking. It stores numeric host addresses in a more human friendly format. DNS is the most common protocol used for name resolution. Pioneer Hospital needs the addition of a DNS server to its new network. This document will explain the benefits of DNS as well as the installation and configuration procedures.

Verify that the listed steps have been completed and click next. In the list of server roles highlight "DNS server" and click next. The application will show a summary of what is to be installed. It should show only a DNS server installation and configuration. After the installation is complete, click next to start the configuration.

The first setting tells the server whether or not to use reverse lookup zones. Reverse lookup zones are translate IP addresses into host names. It is not needed for the Pioneer network, so the first choice should be selected.

Because this is not a public DNS server, and will only be used for the local network, this server will maintain the zone. The next setting reflects this. Next, the zone name is created. This should be the registered domain name for Pioneer Hospital (pioneerhospital.org) with the name of the local domain (corporate) making the zone "corporate.pioneerhospital.org". Because this server is maintaining the zone, dynamic updates are not needed at this time.
