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 draft provides the results of a technical survey of several ISPs about their actual or planned IPv6 deployment strategies. The document has an appropriate Security Considerations section which, essentially says, the document has no security impacts. Russ Mundy
