I have been selected as the DNS Directorate reviewer for this draft. The
DNS Directorate seeks to review all DNS or DNS-related drafts as
they pass through IETF last call and IESG review, and sometimes on special
request. The purpose of the review is to provide assistance to the ADs.
For more information about the DNS Directorate, please see

This document references the DNS as one of multiple possible name
spaces for Name-Based UUID Generation. It has no considerations that
reflect on the DNS.

Previous iterations of this draft have been reviewed by the DNS Directorate
for the -08 [1]  and -09 [2] versions of this draft.

The changes between -09 and -10 address specific comments from the ATART
review and make some clarifying changes to the document which do not
appear to have a substantive impact on the specification.

Issue:

I would like to note that the issues noted in the DNSDIR -08 review [1], namely:

  "Section 5.3, 5.5 and 6.5 refer to "a canonical sequence of octets in
   network byte order". It is not specified what that canonical sequence
   is nor is there a reference to a document that specifies the canonical
   sequence for any of the name spaces."

and 

  "Section 6.5 also has this:
     *  UUIDs generated at different times from the same name in the same
        namespace MUST be equal."
        
do not appear to have been resolved in -09 or -10 versions of this document.

The suggestions made in the -08 review on how to to resolve this issue appears
not to have been resolved in any tangible manner in the subsequent document
versions
