Document: draft-ietf-dnsop-7706bis-07 Reviewer: Ines Robles Review Date: 2020-02-28 IETF LC End Date: 2020-02-28 IESG Telechat date: Not scheduled for a telechat Summary: The document is well written, it supplies appendixes with examples. This document describes a method for the operator of a recursive resolver to have a complete root zone locally, and to hide queries for the root zone from outsiders, at the cost of adding some operational fragility for the operator. I have some minor questions. Major issues: None Minor issues: None. Nits/editorial comments: 1- Appendix B.5: it seems that the link is not valid: This link worked for me: https://knot-resolver.readthedocs.io/en/stable/modules-rfc7706.html. Questions: 1- It seems that this document replaces RFC7706, but the document states that it updates RFC7706, is that correct? 2- Abstract: "The cost of adding some operational fragility for the operator", Does it introduce security considerations that have to be mentioned? 3- Section 1: "Research shows that the vast majority of queries going to the root are for names that do not exist in the root zone." - Do you have some references to that research that can be added to the draft? 4- I would expand KSK to Key signing key (KSK). 5- Should this draft add a reference to rfc8499? Thank you for this document, Ines.
