I have reviewed this document as part of the Ops area directorate's ongoing effort to review all IETF documents being processed by the IESG. These comments were written primarily for the benefit of the Ops area directors. Document editors and WG chairs should treat these comments just like any other last-call comments. Summary: This document describes the method for any organizations to send queries to understand the received unsolicited probing packets. Issues: - Are those queries generated automatically? - If the queries are generated automatically, does it require routers upgrade to support the auto-generating of those queries? - If the queries are generated manually, the draft should give some detailed examples since those queries will be generated by people not coming to IETF. - Today, most routers ignore the Internet probes they don't support. What are the problems of ignoring them? Best Regards, Linda Dunbar
