Hello, 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. The summary of the review is Ready. The Security Considerations section is a bit light but adequate. It would be good if the authors could make a statement similar to that made in RFC 7432. Something like, "Security considerations discussed in [applicable RFCs] apply to this document. ... This section describes additional considerations." Best regards, Chris
