... a possible 227 ASs could start to CIDRize.
I doubt that the administrators of all these ASs are on the BGPD mailing list. Therefore, we need to assume that administrators of the Network Service Providers (e.g. regional networks) that connect to these sites to the Internet have to work with these ASs directly. I also think that requiring in the near term all these 227 ASs to perform site-level aggregation by themselves is not very practical (for one thing this would require all these ASs to move to BGP-4). That seems to leave us with only one feasible alternatives -- proxy aggregation, where a CIDR-capable provider generates aggregates on behalf of its clients that are not CIDR-capable. As a way of trying to identify "easy" target first, let me suggest that each provider who is on the BGPD mailing should identify pure stub sites served by the provider. Once identified, the provider can perform proxy aggregation for such a site with no negative impact. Yakov.
