Looking at the number of autonomous systems in the IPv6 routing table and the total number of routes, it looks like it will shake out somewhere in the neighborhood of 3-5 prefixes/ASN. Since there are ~35,000 unique ASNs in the IPv4 table, I figured simple multiplication provided as good an estimate as any at this early time.Deaggregating of IPv4 announcements is done for traffic engineering and to fight ddoses (just the attacked /24 stops being announced to internet). I think some people will just copy their v4 habits into v6 and then we might have explosion of /48's. I wouldn't be so sure about just 3-5 prefixes/ASN.
Not that many people are de-aggregating in anticipation of the DDoS. Temporary de-agg during DDoS is not relevant to discussions on global table sizes. -- TTFN, patrick
