Last Call Review of draft-klensin-idna-rfc5891bis-07
review-klensin-idna-rfc5891bis-07-opsdir-lc-dunbar-2024-10-22-00

I have reviewed this document as part of the Ops area directorate's ongoing
effort to review all IETF documents being processed by the IESG.  These
comments were written primarily for the benefit of the Ops area directors.
Document editors and WG chairs should treat these comments just like any other
last-call comments.

The document provides valuable guidance but also highlights significant
operational complexity for DNS registries. Ensuring compliance with the
recommendations, preventing security risks like homograph attacks, and handling
Unicode updates will require considerable operational resources. Can the
document recommend some tools to alleviate the operation complexity such as
automating Domain Name validation and filtering? or tools to detect and prevent
Homograph Attack Detection?
