Shepherd writeup

1. The draft is informational. This is the proper type because the draft
describes and analyses pros and cons of different deployment scenarios. The
status is indicated in the draft page header.

2. Technical summary:

This seems fine to grab from the document.

Working group summary:

The draft started its life as draft-palet-v6ops-464xlat-deployment in October
2017, then evolved into draft-palet-v6ops-nat64-deployment in March 2018 as a
NAT64 deployment guideline document intended to be BCP. It was adopted as a
working group document as draft-ietf-v6ops-nat64-deployment in July 2018 with
changed intended status to Informational.

The dicussions in the WG has been supportive of the draft, the author has taken
feedback/suggestions into account and over time evolved/progressed the document
during productive discussions. There has been no general opposition to the
draft itself apart from people opposing on principle on DNS64 "breaking"
DNSSEC. That is not the fault of this draft and this draft suggests no
technological changes.

Document quality:

The document describes technology implemented by numerous networks and devices,
primarily in mobile networks. The author proposes this technology to be used in
more deployment scenarios and that's the motivation for this draft, to analyse
the deployment considerations for other types of network types. The document
has received substantial technical and stylistic feedback and I believe the
document is in good technical shape. The RFC editor might have some
linguistic/grammar/stylistic work to do on this draft, but I believe this is
normal when the author is non-native english speaker/writer.


Shepherd: Mikael Abrahamsson

3. I (Mikael Abrahamsson) has actively participated in review of this document
as a WG member before being asked to shepherd the document. I have experience
in using the technology described in the document and I believe the document is
in good technical shape as is ready to be progressed.

4. The document has received feedback from at least 10 WG members over time and
in the last call approximately 5 people publically said they had reviewed the
document and proposed changes/enhancements (typically minor things and proposal
for adding text) and expressed support for the document being useful and should
be progressed. There was no opposition during WGLC.

5. I do not think the document needs broader review. The document is
informational and describes an overview of already existing technology and
considerations for deploying these technologies in different combinations. It
doesn't propose anything new.

6. I do not have any technical concerns regarding this document.

7. The author has publically stated he is not aware of any IPR regarding the
draft contents.

8. There are no IPR disclosures that I could find.

9. There were no public opposition to this document. Having participated in the
WG for over 10 years I do not believe there is any significant opposition to
this document.

10. There has been no publicly expressed discontent with the document.

11. The document uses SHOULD/MUST, I do not know if this is appropriate for an
informational document.

12. I do not believe the contents need any such review.

13. The document has normative/informative sections. There are other links in
the document that are not part of these sections, for instance that links to
example software implementations.

14. The normative references are all already published RFCs.

15. No downward references.

16. From the IANA considerations section of the document:

"   This document does not have any new specific IANA considerations.

    Note: This section is assuming that is resolved, otherwise, this section may include
    the required text to resolve the issue.

I do not know how to resolve this.
