manu tman: What I meant is roughly around the line of https://tools.ietf.org/html/draft-bortzmeyer-dprive-resolver-to-auth-01#section-2 . e.g if you operate a resolver in strict mode, and DoT fails (connection to port 853, fail to validate SPKI) while the name of the name server indicates that DoT is supported. The resolver should fail. In opportunistic mode, the resolver will fallback onto port 53. The operator of the resolver will be setting the mode of operation. Hello, Ah, that makes sense, my reading was to allow the resolver to use 853 in oportunistic mode even when SPKI validation fail. I've to reread the text...

Hello, for many years I run a dnscurve proxy [1] infront of my nameservers. Worked perfect but virtually nobody used the encryption feature. So, the draft *is* interesting to me... two points comes to my mind while reading the draft: 1. key rotation is hard. 2. what's the reason for "In opportunistic mode, the resolver MUST use the authoritative name server despite the failure." ? A server operator can't distinguish between a resolver in strict mode an a resolver in opportunistic mode TOGETHER with a failure (on server side?) An other option is to force any resolver supporting "dot-" names to fall back on port 53.

Hi all, I have captured in a draft the mechanism I used during IETF 103 hackathon and which is available aan experimental module in knot-resolver[0]. I was taken short with time before cit-off date, but I hope this will better explain how it works.

The fingerprint can thereafter be used to validate the certificate received from the DoT server as well as being able to discover support for DoT on the server.
