How many ASs are out there?

Mon Oct 5 15:50:06 UTC 1998

Are all these "active"?  I know sometimes in this business that mergers
and other consolidations cause one company or organization to "fold"
more than one autonomous system into a single autonomous system.  Is
there any way to trace which AS #'s are dormant, retired, no longer in
use, etc.?

Or is this basically unknowable?

   Well it looks like they (ARIN) are up to about 11554.  This AS was
   the last
   created (Friday 10-1) according to the ARIN ASN database accessible
   from
   "whois".

   Hi,

   Can anyone tell me how many AS are as October of 1998. I know
   there were around 700 registered ASs in the Internet at the
   beginning of 1994. [pag 178 of Huitema-93]

   Is there a web page with that Information?

   Thanks,

   Alejandro
