the proper persistent way to do DNS client configuration is in a following section. nameserver 8.8.8.8 nameserver 8.8.4.4 If you no longer need this configuration and wish to purge all IP configuration • Nameserver Address Nameserver Addresses represent the IP addresses of Domain Name Service (DNS) systems, which resolve network hostnames into IP addresses. There are three levels of Nameserver Addresses Addresses, which may be specified in order of precedence: The Primary Nameserver, the Secondary Nameserver, and the Tertiary Nameserver. In order for your system to be able to resolve network hostnames into

your system will not be able to reach any hosts beyond those on the same network. • Nameserver address: Nameserver addresses represent the IP addresses of Domain Name Service (DNS) sys- tems, which resolve There are three levels of nameserver addresses, which may be specified in order of precedence: The primary nameserver, the secondary nameserver, and the tertiary nameserver. So that your system can resolve resolve network hostnames into their corresponding IP addresses, you must specify valid nameserver addresses that you are authorized to use in your system’s TCP/IP configuration. In many cases, these addresses
