DNS COMMANDS

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-servercommand and domain lookup is enabled with the ip domain-lookupcommand.
