Re: [Int-area] [5gangip] Fwd: New Version Notification for draft-herbert-ipv6-prefix-address-privacy-00.txt

Jon,

Thanks for the reference. I think that both spatial and temporal
characteristics should be part of strong privacy addresses. Will update the
draft to mention those.

One thing that I'm not sure how to quantify yet is the effects of using
addresses for narrow purposes like a single flow. For instance, if a packet
is seen with some address that might not be useful as a target of attack by
trying to connect to the address. No application would be listening on such
addresses (although this does make ICMP interesting, like whether there
should be a response to echo request).
