    This is bad advice, it's waaaaay more complicated. If you run your own personal recursive DNS server on 127.0.0.1, then by default TLD operators can track the websites that you visit and domains you email. A shared cache can anonymize you at that layer.https://twitter.com/paulvixie/status/1232868522071474177 …

    the most private DNS service you will ever use is 127.0.0.1, and any windows or linux or bsd system can do it for you. https://twitter.com/AnachronistJohn/status/1232847256040169474 …

        that's not how this works, even if your upstream RDNS provider isn't using ECS (EDNS Client Subnet). still, we'll add a blender (a "DNS Ring") to solve this problem decentrally, just for you and others who believe as you do.

        It is absolutely how it works and your reply here isn't even coherent enough to refute. By default, running a resolver locally will expose the domains that you query to TLDs. ECS has nothing to do with this.

        Except the fact that's indeed more complicated to run your very own resolver, everything else you just wrote is wrong (about the TLD operators and email). It seems that you don't understand basic DNS and SMTP concepts.

        Ok. Here you go: TLD operators will never see my CNAME, AAAA and A DNS queries - they will only get NS queries from my local resolver. My mail client will only resolve my SMTP server and forward all my emails to that server (assuming that I'm not using a web client).

        This tweet by @paulvixie was mostly inspired by Mozilla's decision to enable Cloudflare DoH by default in FireFox. I asked this already a lot, and nobody seems to be able to give me an answer: Why should people trust CloudFlare more than their ISP with their DNS data?

        Especially given the fact that end-users have a legal contract with their ISP, but FireFox end-users have no contract with CloudFlare. From a legal position, end-users are in a far weaker position with this Mozilla/CloudFlare deal.

        Who do you use for a recursive revolver?

        I think he is saying if you use something like Cloudflare DNS (or anyone else) they act as an intermediate cache between you and the TLD providers. Question is: who do you trust?
