"stateless" with "constant" and "consistent".  SLAAC doesn't need
to generate the exact same address everytime the system is started.

No - but it is *phenomenally useful* if it does. Changing addresses
is only ever something you want in very specific circumstances.

You'll love RFC 4941 as implemented by Windows Vista and later.

The fact that MS chose to use that as the default with Vista is odd, and I
think a bad choice, but RFC4941 is not a bad thing in itself. It is an
alternative that makes good sense in some contexts - but not, I think, in
most
contexts.


While I was initially inclined to agree, operating this way does allow some
interesting capabilities - and I would be very interested in hearing from
someone @MS as to their thinking behind this decision.
