CLI - This example sets a default domain name and a domain list.

However, remember that if a domain list is specified, the default domain

name is not used.

Configuring Static DNS Host to Address Entries

You can manually configure static entries in the DNS table that are used to

map domain names to IP addresses.

Command Usage

• Static entries may be used for local devices connected directly to the

attached network, or for commonly used resources located elsewhere

on the network.

• Servers or other network devices may support one or more

connections via multiple IP addresses. If more than one IP address is

associated with a host name in the static table or via information

returned from a name server, a DNS client can try each address in

succession, until it establishes a connection with the target device.
