It is basically still the same that Mockapetris designed, or it was like this in 2004..2005 at least. We have seen many new types and extensions and clarifications (many early after the DNS RFCs 1035+ were published, for example RFC 1122, "Requirements for Internet Hosts -- Communication Layers"), like EDNS to extend the DGRAM packet size and such, and then luckily someone from the IETF really waved through transport layer security for DNS, via TCP and also via DTLS, which made me really happy. (RFC 8310, and 7858 (TCP) and 8094 (UDP).) There were a lot of RFCs regarding zone transfer, i have to admit that i never read those, as i never had anything to do with the server side of DNS. But the DNS concept by itself scales still and is unchanged?!? I would expect that in the future more and more software becomes capable to follow chains of trust from zone to zone upwards, so that individual zones can use zone-specific TLS certificates, signed only by zones higher up the layer... or a member of the CA pool, the root zone is pretty much U.S.A., which is possibly a bit unfair. --steffen | |Der Kragenbaer, The moon bear, |der holt sich munter he cheerfully and one by one |einen nach dem anderen runter wa.ks himself off |(By Robert Gernhardt)
