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. This document is really good, it summarizes the IPv6 security issues from multiple RFCs. I think IETF should do more of this kind of summary documents that collect high lights from multiple RFCs, to make it easier for network operators. Linda Dunbar
