I have been selected as the DNS Directorate reviewer for this draft. The
DNS Directorate seeks to review all DNS or DNS-related drafts as
they pass through IETF last call and IESG review, and sometimes on special
request. The purpose of the review is to provide assistance to the ADs.
For more information about the DNS Directorate, please see

I did a review of -16 and marked it ready.
An informative reference to RFC 9499 - DNS Terminology was added, thanks!

An issue was interoduced in -17:
The pattern for email-address was changed to '.+@.+'.
This was probably done in response to the ARTART review.
I'm not an expert in email addressing, but this seems way too lenient.

I'm marking this as "Ready with issues", noting that I have no idea how to address the issue.
