IP address total by country: 1990, 2000 and 2009
The rise of China
Recently I found BGP Expert site, which is a nice Internet routing reference. Once a month the site gathers a list of all the allocated IP addresses around the world from the respective authorities and dumps them into a database. The database is queryable via the Addresses Per Country page.
...the number of IP addresses used in every country of the world. The numbers are generated from information published by the Regional Internet Registries (AfriNIC, APNIC, ARIN, LACNIC and RIPE NCC) published on their FTP servers.
Using this query page, I saved the results from 1990, 2000 and 2009 to a text file, imported into MS Excel, imported again into Google Docs, and finally added a Google Docs Map widget. Here are the results:

China is on the rise!
