I've just done a quick read of yesterday's -04 update. I think §5.0 could benefit from a reference to RFC 2308 to clarify that it's talking about negative answer caching. It also says: > A DNS API server SHOULD respond with HTTP status code 415 > (Unsupported Media Type) upon receiving a media type it is unable to > process. why not "MUST" ? In §7.1, the wire format description which only refers to RFC 1035 could be read as too prescriptive w.r.t. the packet length since it's limited to 512 bytes in RFC 1035. There's no need for that limitation, but consideration should be given to how a DNS API Server that is actually a proxy between DOH and real wire format should behave in the presence of a longer packet that isn't accompanied by an EDNS OPT RR.
