    If you want to snoop on DNS queries, you should get permission from the owner. Period. The mental gymnastics to rationalize not needing permission, or claim that isn't the issue have been quite impressive.

        Do you get permission from owners of software before you track down problems? We know you don’t, and there is great value in what you do. If you were made responsible for maintaining the security of an Internet connection, DNS logging would be an essential.

        In fact, when people become aware of the disaster that is third-party ads and tracking, they want their own devices’ DNS logs made visible

        Just to be clear, can you clarify which owner you're referring to? The owner of the remote site, the owner of the client device, or the owner of the DNS server(s)? Or is it any/all of the above?

        If you're at the point that you're litigating what "owner" means, just stop and get permission 😛 Don't worry, you cannot have too much permission to snoop.

        This won’t age well if Google point DoH at their own servers in the future 😅

        If you're at the point that you're looking up the word "owner" in a dictionary to decide if you need permission or not..... you need permission 😛

        Chrome will ask permission to test DoH with Google Public DNS?

        https://www.chromium.org/developers/dns-over-https … is the experiment plan. They're only planning to test DoH when you're using a resolver that supports it. So yes, if you use 8.8.8.8 already, Chrome will use DoH with 8.8.8.8.
