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?
