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

Document is in a good shape and nearly ready. The only issue I could spot is a lack of security considerations around write access to enhanced-dad/enable and enhanced-dad/auto-resolve nodes. As far as I can tell unauthorised access to auto-resolve could result in ND messages being dropped and effective denial of service.
