3. Specify the address of one or more name servers to use for name and
address resolution.
You can specify up to six name servers. Separate each server address 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 back-
up servers are queried.
ip name-server server-address1 [server-address2 ...
server-address6]
(Optional) Enable DNS-based host name-to-address translation on the
wireless device. This feature is enabled by default.
If your network devices require connectivity with devices in networks that
you don’t control name assignment for, you can dynamically assign device
names that uniquely identify your devices by using the global Internet
naming scheme (DNS).
ip domain-lookup
4. Return to privileged EXEC mode.

5. Verify your entries.
show running-config
(Optional) Save your entries in the configuration file.
copy running-config startup-config
If you use the wireless device IP address as its host name, the IP address is used
and no DNS query occurs. If you configure a host name that contains no periods
(.), a period followed by the default domain name is appended to the host name
before the DNS query is made to map the name to an IP address.
The default domain name is the value set by the ip domain-name global
configuration command. If there is a period (.) in the host name, Cisco IOS
software looks up the IP address without appending any default domain name to
the host name.
• To remove a domain name, use the
no ip domain-name name global
configuration command.
• To remove a name server address,
use the no ip name-server
server-address global configuration command.
• To disable DNS on the wireless device, use the
no ip domain-lookup
global configuration command.
