Setting Up DNS

Beginning in privileged EXEC mode, follow these steps to set up the wireless device to use the DNS:
Command
Step 1
configure terminal
Step 2 ip domain-name name
Step 3 ip name-server server-address1
[server-address2 ...
server-address6]
Step 4 ip domain-lookup
Step 5
end
Step 6
show running-config
Step 7 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.

Default DNS Configuration
Default Setting
Disabled.
None configured.
No name server addresses are configured.
Purpose
Enter global configuration mode.
Define a default domain name that the software uses to complete unqualified
host names (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 Dynamic Host Configuration Protocol
(DHCP) server, then the default domain name might be set by the BOOTP or
DHCP server (if the servers were configured with this information).
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 backup servers
are queried.
(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 for which
you do not control name assignment, you can dynamically assign device names
that uniquely identify your devices by using the global Internet naming scheme
(DNS).
Return to privileged EXEC mode.
Verify your entries.
(Optional) Save your entries in the configuration file.
