Re: How many ASs are out there?

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?

Try ftp://ftp.arin.net/netinfo/asn.txt but note that some blocks of AS numbers are allocated to the other regional internet registries (RIPE, APNIC) and that there are some gaps in the list so not all 11558 AS numbers have been assigned. It is, perhaps, interesting to note that a snapshot of a "full" routing table only contains just over 4100 autonomous systems including, interestingly enough, five from the "IANA-RSVD2" range of private AS numbers (64605, 65000, 65050, 65520 and 65521). --James
