Hi, Brian,

My apologies for the delay in my response. Please find my comments

I've checked with a few folks, and it seems that the suggested text
would make everyone happy, except for the sentence that says "As a
result, networks will need to plan for and deploy IPv6 and its security
mechanisms.", on the basis that this is not the document to make a case
for v6 deployment. The suggestions has been to remove that sentence, and
apply the rest of your proposed text (or, alternatively, to tone down
that sentence).

For simplicity sake (and because I'm not sure how one would tone that
one down), my suggestion would be to apply you proposed text, modulo
that sentence.

Would that be okay with you? -- If not, please do let me know, so that
we can try to find a way forward that keeps everyone happy.

Thanks so much!

Best regards,
