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

Hi,

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.

Thanks,

Jon
