Document: draft-ietf-ntp-using-nts-for-ntp-23 Reviewer: Dan Romascanu Review Date: 2020-03-09 IETF LC End Date: 2020-02-28 IESG Telechat date: 2020-03-12 Summary: Ready. A very clear, well written, nicely organized document. While reviewing version -22 of the document I had a minor non-blocking comment about marking unused entries in the tables in Sections 7.6, 7.7, 7.8 that may be used for future extensions as 'Reserved for Future Standard Use'. An exchange of mails with the editors clarified that they are following the recommendations at https://www.iana.org/help/protocol-registration>, under "Lists Versus Tables”, which say: > "For an example of an IANA Considerations section that uses tables, see RFC 6940. For an example that uses lists, see RFC 5804.” While I still believe that explicit marking entries in the tables as 'Reserved for Future Standard Use' makes things more clear and avoids future problems, I can live with following the IANA recommendations above. This was a minor non-blocking issue anyway. Major issues: Minor issues: Nits/editorial comments:
