Google officially announced its own DNS-over-HTTPS (DoH) experiment in Google Chrome recently. Google published a blog post on Tuesday providing more detail on the functionality of DoH and that it will be included in Chrome 78.
Chrome won’t just change the user’s DNS provider. When Chrome makes a web request, it will then check a list for friendly DoH that are vetted by Google. Only if it is on that vetted list will it go and switch to DoH. Google is making the service available on all Chrome-supported platforms, excluding Enterprise customers, iOS, and Linux for the time being.
For the time being, this will roll out to only a part of the Chrome users as a sort of beta test. For those who do get opted into this, you can opt-out by disabling the flag. This is accessible in Chrome 78 by typing the following into your address bar: “chrome://flags” and search for “Support for HTTPSSVC records in DNS” where you can then opt out.
Chrome 78 is due for release in October 2019.
