Does the abundance of AS numbers indicate Internet growth? Doug Madory indicates that “ASNs vary dramatically in size, from large companies to small non-profits”. Actually, many of the ASNs are just non-active. They are registered but do not advertise any IP addresses, or just do not pull or push any traffic.
At DiViNetworks we are very interested in mapping active ISPs in different countries; after all – that’s our target market. Luckily, tons of traffic traverses our DiViCloud network. We analyzed it to obtain the number of real active networks in all countries.
If you are interested in obtaining per-country numbers, please email me.
