Setting a Profile's DNS Configuration

Domain Naming System (DNS) DNS is a hierarchical naming system for resources connected to the Internet or a private network. Primarily, DNS resources translate domain names into IP addresses. If one DNS server doesn't know how to translate a particular domain name, it asks another one until the correct IP address is returned. DNS enables access to resources using human friendly notations. DNS converts human friendly domain names into notations used by different networking equipment for locating resources.

As a resource is accessed (using human-friendly hostnames), it's possible to access the resource even if the underlying machine friendly notation name changes. Without DNS, in the simplest terms, you would need to remember a series of numbers (123.123.123.123) instead of an easy to remember domain name (for example, www.domainname.com).

To define the DNS configuration:

1. Select Configuration > Profiles > Network.

2. Expand the Network menu to display its submenu options.

3. Select DNS.

   

4. Set the following Domain Name System (DNS) configuration data:

   Domain Name	Provide the default Domain Name used to resolve DNS names. The name cannot exceed 64 characters.
   Enable Domain Lookup	Select the check box to enable DNS. When enabled, human friendly domain names are converted into numerical IP destination addresses. The radio button is selected by default.
   DNS Server Forwarding	Select this option to enable the forwarding DNS queries to external DNS servers if a DNS query cannot be processed by local DNS resources. This feature is disabled by default.

5. Set the following DNS Server configuration data:

   Name Servers

   Provide a list of up to three DNS servers to forward DNS queries if local DNS resources are unavailable. The DNS name servers are used to resolve IP addresses. Use the Clear link (next to each DNS server) to clear the DNS name server's IP address from the list.

6. Select OK to save the changes made to the DNS configuration. Select Reset to revert to the last saved configuration.
