Sure. How do they compare to the total cost of the IPv6 conversion
excluding SLAAC? (Btw, for the folks who said that enterprises may
not want privacy-enhanced addresses -- that isn't clear to me. While
they may want it turned off internally, or even when roaming internally,
I suspect that many companies would really want to avoid having their
employees tracked when they're traveling. Imagine -- you know the CEO's
laptop's MAC address from looking at Received: lines in headers. (Some
CEOs do send email to random outsiders -- think of the Steve Jobs-grams
that some people have gotten.) You then see the same MAC address with
a prefix belonging to some potential merger or joint venture target. You
may turn on DHCPv6 to avoid that, but his/her home ISP or takeover target
may not.)
