Chapter 2: Accessing and Managing the System
Creating a DNS Name Server List
A DNS name server list with up to three IP addresses in the list can be created. When
more than one address is listed, the system uses the order specified to determine the
order of priority for name resolution. To create a DNS name list, use the ip nameserver
command in Privileged Exec mode.
To remove one or two of the name servers, re-enter the ip nameserver command without
their IP addresses. Specifying the command replaces all the existing nameservers with
the new IP addresses. To remove all of the nameservers, use the no version of the
command:
ip nameserver ipaddr {ipaddr2 ipaddr3}
no ip nameserver
For example,
(SafeGuardOS) # ip name-server 1.1.1.1
(SafeGuardOS) #
Displaying DNS Information
Use the show dns command in Privileged Exec mode to display the current DNS
configuration:
show dns
For example,
(SafeGuardOS) #show dns
DNS configuration:
ip domain lookup
ip domain name Alcatel-Lucent.com
ip name-server 1.1.1.1
(SafeGuardOS)
Syntax Description ipaddr Specifies the IP address of a name server.
ipaddr2 (Optional) Specifies the IP address of the
secondary name server.
ipaddr3 (Optional) Specifies the IP address of the
final name server.
