This is a list of the "Top 50" players who if CIDRizing at the AS level
could make a significant gain in the reduction of the size of Internet
routing tables. This may be an over-estimation but it is hoped that
this can act as an incentive for the "Top 50" and others to look at
their CIDR capability. This is a revival of report that used to be
posted in the early days of CIDR deployment (we even had a cidrd list
and working group then).
This looks purely at the classful routes in the system and shows what gain if
cidrizing at the AS-level could be made by forming an aggregate.

P.S. Same caveat about AS name mappings not working quite right yet.
P.P.S. Unless there are loud objections I plan to automate this again soon.
