Linux Users:

8.8.8.8  is base – 8.8.4.4 is head (*secondary)

$ sudo vi /etc/resolvconf/resolv.conf.d/base

Then put your nameserver base address: nameserver ip.ip.ip.ip Save it.

$ sudo vi /etc/resolvconf/resolv.conf.d/head

Then put your nameserver head address: nameserver ip.ip.ip.ip Save it.

$ sudo vi /etc/dhcp/dhclient.conf 

Then add base address here prepend domain-name-servers ip.ip.ip.ip; or supersede domain-name-servers ip.ip.ip.ip; ## if the name is not resolved by ip.ip.ip.ip, ## then the request falls back on the other server.

Finally update resolvconf:

$ sudo resolvconf -u

$ sudo service network-manager restart

Choose the one that meets your needs and way you go.
