Betreff: [NetBehaviour] size of the internet

I've done some ciphering and estimate the size of the internet.

If each gigabyte weighs one tenth a gram and is gaseous and blue, and the container for the gas is shaped like a giant corn cob plate, then the internet is about two coffee tables and a late spring snow storm on the plains sized.

- Jason Nelson from [NetBehaviour] size of the internet





From the Caida.org site:

The graph reflects 926,201 IP addresses and 2,000,796 IP links (immediately adjacent addresses in a traceroute-like path) of topology data gathered from 22 monitors probing approximately 865,000 destinations spread across 77,678 (50% of the total) globally routable network prefixes.

Graphing dimensions of peering richness and geographic information reveals the highly "core-centric" nature of certain ASes based in North America. While ISPs in Europe and Asia have many peering relationships with ISPs in the U.S. there are fewer links directly between ISPs in Asia and Europe. Both technical (cabling and router placement and management) as well as policy (e.g. business cost models and geopolitical considerations) factors contribute to peering arrangements represented in this graph.
