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: <https://knot-
   resolver.readthedocs.io/en/stable/modules.html#root-on-loopback-rfc-
   7706>

  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.
