The hosting appliance can function as a Domain Name Service (DNS) server for your network, resolving hostnames (such as xyzcorp.com) to IP addresses (such as 192.168.1.1), and vice versa. Note: In order to provide name service on the Internet, you must register your domain name with a registrar or your network administrator, and configure the domain to use this appliance as its authoritative name server.

The DNS hostnames and IP addresses are stored as host records in a database. As queries for hostnames or IP addresses are received by the hosting appliance, the DNS service uses these host records to return the requested DNS information to the requesting client.

The hosting appliance enables you to do the following:
