DNS Commands
These commands are used to configure Domain Naming System (DNS)
services. You can manually configure entries in the DNS domain name to
IP address mapping table, configure default domain names, or specify one
or more name servers to use for domain name to address translation.
Note that domain name services will not be enabled until at least one name
server is specified with the ip name-server command and domain lookup
is enabled with the ip domain-lookup command
