That wouldn't constitute a complete answer because there are MANY local ISPs that aggregate under a regional. Also, not all regionals (yes, I've found some exceptions <Qwest?>) use BGP either. Then there is the old route pre-fixing problem. Not many ISPs, smaller than /19, are going to be doing effective ASN's either.

how many active ASN's are there?
I was actually thinking along IAP (Internet Access
Provider) lines. But,
most folks lump ISPs and IAPs in the same breath.
