Reviewer: Geoff Huston Review result: Ready The draft makes no reference to the DNS, and as such there is little for this DNS Directorate reviewer to comment on from the perspective of the DNS. This is also a informational RFC, and the review questions for such an RFC are necessarily focused on the clarity of the descriptions contained in the document as well as attention to the accuracy of any calims made in the document. From this reviewer's perspective the document is clear and thew assertions appear to be reasonable. AS a purely personal comment, which the authors may chose to pay heed to or just ingore, the document makes absolutely no reference to the NTS protocol. Since the presumed attack is an attack on the NTP transactions, when what are the attributes of Khronos that make it an attractive alternative to NTS? However, to the extent that this is not a document that touches in any substantive weay on the DNS and this is a DNS directorate review, there is nothing that is worthing of flagging for further attention in this document -- last-call mailing list last-call@xxxxxxxx https://www.ietf.org/mailman/listinfo/last-call
