If you want to suggest some edits to make clear that we are talking
about prefixes, please do so. I am probably too close to the document
to see where that would be useful.

Clarifying question: if prefixes are what are being validated
why does the name mention addresses and the text "current SAV
mechanisms" (where A==address presumably)?
Ta,
S.
they will be using as source address for packets they will be
forwarding. These are not the individual addresses of users. And,
conversely, this is exactly the information one needs to perform
source address spoof prevention. (Whether the proposed / expected
mechanisms will actually provide improved information is part of what
has to be determined.)
Further, we have specified that the problem and requirements will be
spelled out before any solutions are examined by the working group.
So we can confirm that there is indeed a problem to solve.
This is not "extend SAVI individual host registrations into ISPs." I
have no problem including privacy in the analysis. But I am much less
concerned than I was (and yes Stephen, I did take your concerns
seriously) when we did the SAVI work.
Yours,
Joel
