1. ASes there are in the world today?
The weekly routing table summary posted here will give you a good approximation, but it does not include AS's that aren't announced on the public Internet. This may or may not be an issue, depending what you are doing with the numbers (for instance, allocated but not announced ASs may not matter if you're looking at BGP performance - but they *do* matter if you're trying to estimate a drop-dead date for 32-bit ASN deployment).
