Sure. Getting IPv6 addresses is easy. Like getting a vaccine. You pay
for it, get pricked, endure and it's all good.

But do you only want to assure that -your- kids to get the vaccine? Or
do you want -everybody- to get the vaccine so that the disease itself
dies out and doesn't haunt you again year after year? If we've truly
learned how to beat the disease, is it not worth it as a matter of
public policy to preemptively provide everybody with the vaccine?

We beat smallpox. Let's beat IPv4. ;-)

Do you have any ideas on how to tell the difference in a relatively
automated manner? I know how to test for whether you hold an
allocation, but I'm not sure how to test for what kind of allocation
holder you are.

If we can't tell the difference, does that negate the value in
preemptive allocation? If it doesn't then let's make an educated guess
as to what size is likely to be useful, recognizing that anyone who
finds they received the wrong size is in no worse shape than they are
without preemptive allocation.
