| 10.2.3 | Describe the ip name-server command
The ip name-server command defines which hosts can provide the name service. You can specify a maximum of six IP addresses as name servers in a single command. To map domain names to IP addresses, you must identify the host names, specify a name server, and enable DNS. Any time the operating system software receives a host name it does not recognize, it refers to DNS for the IP address of that device.
