Domain Name System Settings

Domain Name System (DNS) is an information service for TCP/IP networks that uses a hierarchical naming system to identify network domains and the hosts associated with them. You can identify a pri- mary DNS server and one secondary server.

Common Commands

set dns domain-name domain-name

Specifies the default domain name for your network. When an application needs to resolve a host name, it appends the default domain name to the host name and asks the DNS server if it has an address for the “fully qualified host name.”

set dns primary-address ip_address

Specifies the IP address of the primary DNS name server.

set dns proxy-enable

This allows you to disable the default behavior of acting as a DNS proxy. The default is on.

set dns secondary-address ip_address

Specifies the IP address of the secondary DNS name server. Enter 0.0.0.0 if your network does not have a secondary DNS name server.

set dns configured-dns-priority [ 0 - 255 ]

Sets the configured DNS priority relative to acquired DNS. These server addresses may be acquired via DHCP (client), PPP, or statically configured. A “DNS learned-server-priority” is assigned to each config- ured interface. By default, configured DNSes have the highest priority (lowest number), then PPP- acquired DNSes, and DHCP-acquired DNSes have lowest priority (highest number).

The default priorities for each type are:

❑Configured DNSes: 10

❑PPP-acquired: 20

❑DHCP-acquired: 30
