DNS over HTTPS (DoH)

DNS over HTTPS (DoH) is rapidly becoming the new standard for securing the privacy of DNS requests, and is being adopted by a number of internet browsers, including Chromium by Google and Mozilla® Firefox. What DoH does is encrypt the DNS requests between the browser and the DNS Server. On the face of it this improved security and encrypting traffic is a good thing, isn't it?

Although DoH offers increased privacy, this is a rather large catch. If you have any DNS based filtering, for instance to block accessing malicious sites, then DoH may circumvent these controls.
