What needs to happen (would solve multiple problems) is that ISPs need to 
announce the "customer allocation size" in something that is scalable, and 
then tools need to adapt to this and not treat IPv6 space as 2^128 
addresses but instead treat it as "customer blocks" of different sizes, 
and do anti-spam handling on these customer block boundaries instead of 
per-IP.
