ip name-server

This command specifies the address of one or more domain name servers to use for name-to-address resolution. Use the no form to remove a name server from this list.

Syntax

[no] ip name-serverserver-address1 [server-address2 … server-address6]

•server-address1- IP address of domain-name server.

•server-address2 … server-address6 - IP address of additional domain-name servers.

Default Setting

None

Command Mode

Global Configuration

Command Usage

The listed name servers are queried in the specified sequence until a response is received, or the end of the list is reached with no response.

Example

This example adds two domain-name servers to the list and then displays the list.
