Interestingly, the Caida data lacks AS numbers issued in the last several 
months, while the data is present in the arin.net and potaroo.net listings. 
Not sure where Caida gets its data, but the other sources would seem to be 
better for the project the original poster had in mind.

It's also more than a bit odd, IMO, to assign a latitude and longitude to 
AS numbers. While some networks are well localized, many others span 
continents. As such, the value of that part of the caida data set seems 
nebulous.
