Hi all, Having seen in draft-ietf-uta-rfc7525bis (-02) that "protocol developers are strongly encouraged to register an ALPN identifier for their protocols", and having the support of the (closed) IETF NNTP WG: https://lists.eyrie.org/pipermail/ietf-nntp/2021-September/thread.html I would like to register TLS ALPN registry entries for Network News Transfer Protocol (NNTP): Protocol: NNTP (reading) Identification Sequence: 0x6E 0x6E 0x74 Ox70 ("nntp") Reference: [RFC3977] Protocol: NNTP (transit) Identification Sequence: 0x6E 0x6E 0x73 Ox70 ("nnsp") Reference: [RFC3977] So as to distinguish mode-switching news server, NNTP makes use of 2 ports (119 for reading and 433 for transit) as described in Section 3.4.1 of [RFC3977]. These ports are named "119 nntp" and "433 nnsp", which is the rationale for the identification sequence. Note that some news servers are already accessible from HTTPS port (443) like <https://news.aioe.org/> or <https://www.eternal-september.org/index.php?showpage=techinfo> (though no web server currently listens there at the same time). So ALPN can really be a great improvement if more and more generalised and used with for instance sslh (a ssl/ssh multiplexer). I am unsure what references are needed to allow the registration. Is the core NNTP reference [RFC3977] enough? Or do you prefer the one for TLS implementation in NNTP [RFC4642] or maybe its update [RFC8143] recommending to follow [BCP195] best practices? I've seen that a (quick) Internet-Draft has been asked for the registration of SIP. Is it really necessary? (seems overkill to me) I for instance do not see such references for the FTP or IRC registrations... Nevertheless, I'm of course fine with your decision. Thanks beforehand for having a look at my request. -- Julien ÉLIE « On appelle ça une insula. C'est une maison où les gens habitent les uns au-dessus des autres… » (Astérix)
