There are currently around 25-30k ASs in the Routing Table, if everyone
who had an AS announced one IPv6 Prefix per AS, this would be like 10%
of what most border routers currently carry. Even if everyone was in the
CW Situation to announce three prefixes this would be < 50% of the
currenty routing table (entries).
