Last Call Review of draft-shore-icmp-aup-06
review-shore-icmp-aup-06-opsdir-lc-chown-2014-01-23-00

Hi,

I have reviewed draft-shore-icmp-aup-09 on behalf of the OPS DIR and believe
the document is Ready.

I believe the guidance presented in the document is useful to publish, and
having the consensus on the subject written up provides a useful point of
reference when certain uses of ICMP are proposed in future draft documents.

A couple of non-blocking nits:

1. One might add at the end of Section 2.3 that filtering of ICMPv6 Packet Too
Big messages has caused problems for IPv6 deployment wrt PMTUD, despite the
advice of RFC4890. There's actually some good material in RFC4890 on ICMPv6 use
cases and issues with its use and its security - is it worth adding a reference
to that in this document?

2. I would suggest putting the "AUP" in a separate section, before Section 5,
perhaps called "Recommended AUP for ICMP" or similar, making Section 2 called
something like "Comments on the existing use of ICMP".  I find the existing
structure a little bit odd - I think the recommendation would sit better as the
conclusion of the document.  That is just a personal preference however.
