Earlier quoted context omitted.
Some ISPs block outbound DNS from customers to anywhere but their resolvers, filtering based on target port. This is a particularly common trick in countries that attempt to censor the internet. It's a lot harder to do that with DNS-over-HTTPS because it looks like normal traffic. That said, in this case ISPs can just null route the IP address of the obvious main resolvers such as 1.1.1.1. I imagine most of the benef…
When we add TLS on top of the protocol, ISPs can only filter based on port at that point. We can run DNS on 443 if that helps, but as you said, static well-known IPs can then be blocked. > I imagine most of the benefit is surely to people who can spin up their own resolvers. There are already many easily run DNS resolvers available. Is there a benefit you see in operating them over HTTPS that improves on that?
And SNI… :(
