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 short doc tells operators that they should no longer have (most) v4 /8's in their bogon filter lists. I'm not sure why that statement needs its own draft, but it seems like an obvious and harmless thing to say. I have no concerns with the doc. -- Sam
