There’s no publishing cycle; the IANA folks just update the doc and publish to the website.

The approvals probably got drowned out during the holiday festivities.  You got approved, so you treat the assignment as official; the website/registry will catch up soon.

Hi folks,

Just following up on this, since I think the 3 week review period has expired.   Can we move forward with publishing this registration, or is there some periodic publication cycle?

Yoav and Nick,

Could you guys approve this?  Since it came from Akamai, I want to abstain.

Subject: [Tls-reg-review] Request to register ALPN ID for DNS-over-TLS


I'd like to request registration of an ALPN ID for DNS-over-TLS (RFC 7858).   The ID will be used, by prior out-of-band mutual agreement, in cases where DNS-over-TLS is used over a non-standard-part (e.g. 443).    The identification sequence will be: 0x64 0x6F 0x74 ("dot").

Rich Salz suggested I survey the dprive working group before doing this, and I have done so[1].  There appears to be support for this, including from one of the authors of RFC 7858, provided it's used by prior agreement on non-standard ports, and not required as part of normal use on port 853.

Please let me know if you have more questions or need more information.
