HTTP/3 support for DNS-over-HTTPS (DNS-over-HTTP/3, DoH3)

Open ammnt opened this issue 3 years ago • 2 comments

Hello,

unfortunately, I could not find any detailed information about the status of DNS-over-HTTPS with HTTP/3 (DNS-over-HTTP/3, DoH3) support here or on the forum. All I know is that filtration engine are now forcibly downgrading the connection protocol to HTTP/2😟

So please add DoH3 support in future releases for all applications with the DNS encryption and filtration🙂

Thank you. Best regards!🎁

Any update of this? HTTP3 support for NGINX is coming soon!🎉

We should do three things here:

  1. Flag to enable HTTP/3
  2. Make a research which HTTP version choosing algorithm cURL uses, it should match Chrome's. If doesn't match, check if it is implemented correctly.
  3. Add h3:// protocol to force HTTP/3 even if HTTP/3 support is not enabled for all upstreams.

Now it’s just a matter of waiting for dnslib’s to be updated for the platforms

I find it disappointing that the newly released adguard iOS 4.4.6 only supports dnslib v2.0.75. I hope they can update dnslib soon to support DoH3 because it was introduced in the soon after released dnslib v2.1.3
