"Cloudflare's mission is to help build a better Internet. We're excited today to take another step toward that mission with the launch of 22.214.171.124 — the Internet's fastest, privacy-first consumer DNS service. This post will talk a little about what that is and a lot about why we decided to do it.
...The problem is that these DNS services are often slow and not privacy respecting. What many Internet users don't realize is that even if you're visiting a website that is encrypted that doesn't keep your DNS resolver from knowing the identity of all the sites you visit. That means, by default, your ISP, every wifi network you've connected to, and your mobile network provider have a list of every site you've visited while using them."
