## Configure a Domain Name Option

You can use this option to set the domain name in the DHCP server configuration parameters. The `no` form of the command deletes the domain name from the DHCP server configuration parameters. This pool-specific configuration parameter is offered to DHCP clients in the pool only when there is no host-specific option for the client. If this option is not configured and there is no host option, the global option is used.

In this example, the domain name for the network is "future."

1. Create the address pool.

       SEFOS# configure terminal
       SEFOS(config)# ip dhcp pool 1

2. Specify the domain name for the network.

       SEFOS(dhcp-config)# domain-name future
       SEFOS(dhcp-config)# end

3. Ensure that the domain name option has been configured.

       SEFOS# show ip dhcp server pools

   The output in switch 1 is:

       Pool Id                         : 1
