Choose a public DNS server for more privacy

You have to prepend a nameserver in resolv.conf file.

Follow this quick guide in KISS mode (Keep It Simple and Stupid).

• create (if not exits) /etc/dhclient.conf file with

interface "eth0" {
    prepend domain-name-servers 9.9.9.9;
}

• for testing purpose

dhclient eth0 -v
cat /etc/resolv.conf

• by this way, it will be the first DNS server to be querying for domain name.

• some public DNS servers easy to remember:
  • 1.1.1.1 (Cloudflare)
  • 9.9.9.9 (Quad9)
• More public DNS servers
