Re: [Last-Call] Dnsdir last call review of draft-ietf-cdni-delegation-acme-03

[frederic.fieau@xxxxxxxxxx]

Hi Vladimír,

In the latest version that was just posted, we've added the following to clarify the situation regarding DNS:

"Note: The delegation object defined in Section 2.3.1.3 of [RFC9115] only allows to specify DNS mappings using CNAME RRs. A future document updating  [RFC9115] could expand the delegation object to also include SVCB/HTTPS-based [RFC9460] mappings."

Thank you,

Regards,

Frederic

Hi,

Thank you for the review. I've noted your comments. AFAIK, there is indeed no impacts on DNS aspects.

Reviewer: Vladimír Čunát
Review result: Ready

So, dnsdir assigned me reviewing this draft, but I basically failed to find DNS in it :-)  And I'm afraid I don't know ACME well, so I'm marking this draft as "Ready" just not to block it on DNS.  Maybe I've just missed it, so point me to the DNS aspects, please.

Still, let me at least comment around this DNS redirection.  The parent RFC
9115 only considers CNAMEs, at a glance.  It feels like for future the SVCB/HTTPS records should be considered a well (in a different draft/RFC).
They were designed with modern web CDN needs in mind, and among other features they support "redirecting" a zone apex, which seems practically important.  For a trivial example, you can't put a CNAME at example.com, only at BLOCKEDexample[.]comBLOCKED
