Even if you get a signal, the reality may be out-of-sync with the signal, for instance because of a problem on the server side (remember AAAAs published without checking IPv6 connectivity works) or on the client side (port 853 blocked). So, in any case, the client has to be ready to encounter a problem and to try a fallback. So, why not an "happy eyeball" (RFC 8305) approach? Check 53 and 853 more or less in parallel and keep DoT if it works. _______________________________________________ dns-privacy mailing list [email protected] https://www.ietf.org/mailman/listinfo/dns-privacy
