DNS Domain Name System or Service is a hierarchical decentralized naming systemservice that translates domain names into IP addresses on the Internet or a private network and a server that provides such a service is called a DNS server. Type following command and click on DNS tab Setup hostname and domain name. See how to configure Linux as a dns client.
