Enables privileged EXEC mode.

Enters global configuration mode.

Defines a default domain name that the software uses to
complete unqualified hostnames (names without a
dotted-decimal domain name).
ip domain-name name
Example:
Device(config)#
ip domain-name Cisco.com
Step 3
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 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).
Specifies the address of one or more name servers to use
for name and address resolution.
ip name-server server-address1
[
server-address2 ...
server-address6
]
Step 4
Example:
You can specify up to six name servers. Separate each server
address with a space. The first server specified is the
Device(config)#
ip
primary server. The device sends DNS queries to the
name-server 192.168.1.100
primary server first. If that query fails, the backup servers
are queried.
192.168.1.200 192.168.1.300
(Optional) Enables DNS-based hostname-to-address
translation on your device. This feature is enabled by
default.
ip domain-lookup
[
nsap
|
source-interface interface
]
Example:
Device(config)#
ip domain-lookup
Step 5
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).
Returns to privileged EXEC mode.
