Mapping Local Internet Control

from the Berkman Center for Intenet & Society at Harvard University

Countries by Network Complexity

Here we list countries by the complexity of the network of autonomous systems within the country. This metric captures the number of connections between asns within the country, weighted by the number of children with more than one parent and by the number of IP addresses at the edges of the network. This metric is intended as a rough metric of the difficulty of controlling which users are able to connect to the Internet and how they are able to connect.

To see the map for a given country, click on one of the lists below and then click on the desired country name. For more information about the methodology used for the metrics and the maps, see the Methods page. For an xml file containing the raw data, including the network connections and the metrics for every country, see the Raw Data page.
