to ASes.While some ASes may have a large number of ip allocations,
and hence a need for more prefixes to be announced, most have rather few
prefixes that need to be announced.On the other hand, as we all know,
many ASes announce far more prefixes than necessary.Here's the top few
in the list when sorted by ratio of prefixes to ASes:country prefixes/ASes
ZA 77.22857143
Something in ZA looks skewed. Can anyone shed light as to why ZA has so
many small prefixes (even with lots of users)? Lack of CIDR? Poor
allocation methods? Clueless ISPs? Thanks, Hank

nearly meaningless ratios.The US is in the 11 range, and ?? comes in
down around 9.-David
