DETAILED STEPS
Table 3 Default DNS Configuration
Feature Default Setting
DNS enable state Disabled.
DNS default domain name None configured.
DNS servers No name server addresses are configured.
Command Purpose
Step 1
configure terminal Enters global configuration mode.
Step 2
ip domain-name name Defines a default domain name that the software uses to complete unqualified
hostnames (names without a dotted-decimal domain name).
Do not include the initial period that separates an unqualified name from the
domain name.
At boot time, no domain name is configured. However, if the wireless device
configuration comes from a BOOTP or DHCP server, then the default domain
name might be set by the BOOTP or DHCP server (if the servers were
configured with this information).
Step 3
ip name-server server-address1
[server-address2 ...
server-address6]
Specifies the address of one or more name servers to use for name and address
resolution.
You can specify up to six name servers. Separate server addresses with a space.
The first server specified is the primary server. The wireless device sends DNS
queries to the primary server first. If that query fails, the backup servers are
queried.
