[rssac-caucus] Results of caucus review of the RSSAC Report on Root zone TTLs

[Daniel Migault]

Hi,

Thank you for addressing the comments. It is also very convienient to have
the new version and the "how comments are addressed" document.

I think it is pretty important to note that TTL values are not so much
documented, so mayby something similar as the editor response below could
be placed in the intro or in section  3.

"Editors’ Response: RFC 1033 has a section on TTLs, which we reference
toward the end.  Based on my familiarity with the RFCs I do not expect
that we’ll find more any specific advice to DNS operators in general, nor
for the root zone in particular."

I agree with the responses.

My response to comments 11'response would be: I agree that the figure is
clear, What I meant was a "formal" relation between TTL values woudl be
helpful to implement a checkzone test to somehow validate the root zone.
Here the comment 11:

11) section 6.4.1 Is there any reason the relation between the different
Time is not expressed.
SOA_Expire + NS_TTL <= ZSK_validity

Editors’ Response: I’m not sure I understand the question.  I think Figure
7 is clear.

Hope it helps,

BR,
Daniel
