> By default all DNS look-ups (that translate a human readable domain name to an IP address) are being conducted by the DNS servers of your ISP. I recommended you change this default behavior.

Even if your DNS servers are not your ISP's servers, your ISP will still know which IP addresses you connect to... I don't see how this increases privacy if you share it with a third party instead (https://www.opennic.org/ in his example).
