CONFIG Commands
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 primary 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 still
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.
Dynamic DNS Settings
These commands are supported beginning with Firmware Version 7.4.2.
Dynamic DNS support allows you to use the free services of www.dyndns.org. Dynamic
DNS automatically directs any public Internet request for your computer's name to your cur-
rent dynamically-assigned IP address. This allows you to get to the IP address assigned to
your Gateway, even though your actual IP address may change as a result of a PPPoE con-
nection to the Internet.
