Regarding DoT, it seems to me that a super simple way for the client to be able to authenticate the server would be to include the server's IP address(es) in the subjectAltName field. This wouldn't require a DHCP extension, and nicely supports opportunistic updgrade. I'm afraid I wasn't paying attention when RFC 8310 was being prepared so I don't know why it excludes iPAddress authentication. Regarding DoH, the DHCP option ought to include a URI template (there isn't a .well-known for DoH). I plan to set up my servers so that misdirected attempts to get web pages from the DoH server are redirected to the relevant documentation; that's much easier if the DoH endpoint isn't at the server root. A URI template usually implies the need for DNS queries to resolve the server name (unless it's an address literal). Would it be plausible to allow the client to assume that the DoH server IP addresses are the same as the DNS server addresses, so it can skip the lookup? I guess that would be too annoying for operators that want their DoH servers to be separate from their normal DNS resolvers, so maybe it's a bad idea :-) Tony. (PS. DoTH is clearly what happens if someone suggests "DoNT" but we do it anyway.) -- f.anthony.n.finch <dot@dotat.at> http://dotat.at/ fight poverty, oppression, hunger, ignorance, disease, and aggression
