I recently heard about DOH (https://hacks.mozilla.org/2018/05/a-cartoon-intro-to-dns-over-https/ …) and was wondering whether I'm the only one shocked by the design. For instance, @jedisct1 what's your opinion about that? @bortzmeyer you look pleased; are you?

I think it’s great and extremely promising. DNS has traditionally been a bottleneck for what CDNs can do to reduce latency. DoH can remove that bottleneck.

From an early reading, I dislike the mandatory TCP + TLS + http boilerplate as opposed to packed datas, inside UDP datagram. Should it even be called DNS? Plus, that's just tunneling DNS inside another protocol.

At least QUIC should remove some of this overhead. Still the same underlying idea about universal HTTP though.

The overhead is negligible, as HTTP/2 provides multiplexing, prioritization, etc. similar than UDP, except better implemented. And it opens new possibilities such as https://tools.ietf.org/html/draft-nottingham-doh-digests-00 …

I agree on that part for http/2. Didn't get the requirement cause only read "dns over https" though.

They call it DNS-over-HTTPS, but the actual specifications mandate HTTP/2, and explain why it wouldn’t make any sense to do it over HTTP.

I have to read the actual draft rather than blog posts. Thanks for your inputs :)

Anyway, you probably got my point. HTTP is *great*, and is the only protocol that keeps evolving anyway (for real, not just by writing RFCs that nobody implements/deploys like all other protocols). Hop on the bandwagon or keep using Compuserve and Minitel.

I guess the last survivor couple is smtp/imap then. Looking forward to have them on http as well!

I strongly disagree on that one. People don’t keep 10years of $applicationlogs

Oh, some companies definitely do, especially DNS logs that are easy to monetize.
