Additionally, you need to subtract out the ones that have gone out of
business.  I was looking thru the ASN list and right off the top found
about 5 that I recognized as defunct within the first 5000.

AlanC {stunned that we just got an ASN in the 2xxxxx range}
There are 11,358 AS's currently announced in the BGP table in my neck of the woods
(http://www.telstra.net/ops/bgp/bgp-as-count.html)

Other folk see 11,332 (AS 286) and 11,330 (AS 818).

The highest AS number being announced at present is AS21949
