Hi,

I have reviewed this document as part of the Operational directorate's ongoing
effort to review all IETF documents being processed by the IESG.  These
comments were written primarily for the benefit of the operational area
directors.  Document editors and WG chairs should treat these comments just
like any other last call comments.

Overall I think the document is Ready with nits.

The subject matter of the document is both good and useful. I believe it is a
good example of the type of work that v6ops should be undertaking. The
Informational nature of the document is appropriate.

I cannot comment on some of the details of the mobile operation as it is not an
area I have high exposure to. However, the points made and the discussion at
the end in Section 7 seem well founded and appropriate, based on the
information presented. Whether it is a complete summary of issues, I cannot
say, but regardless the document appears a useful snapshot of current issues.

The draft has only required minor edits since the WGLC. There was some
discussion around the -02, e.g. on Telenor Norway’s apparent choice to only use
IPv6 PDP.

There are some nits to fix, around issues with the use of English language, but
these are small in number and minor, e.g. in 5.1 "If the applications can't
support IPv6, the service is likely failed.”  I don’t believe that any
corrections would lead to a change in interpreted meaning of the document.
