I am installing a pivpn, on my raspberry pi, at my home network and it asks me for the DNS provider for my VPN Clients. I am concerned about the privacy of the DNS. What can I do to ensure the maximum anonymity of my vpn users. Some options I have already considered are:
- using 18.104.22.168
- using some free DNS like FreeDNS, DNS Watch etc
- Google DNS (which I do not really want to use)
Please elaborate why your something you propose is better than others.
