Of the top 15 ASes, 14 are based in the U.S., and one is based in Canada. While ISPs in Europe and Asia have many peering relationships with ISPs in the U.

Core AS Internet Cooperative Assocation for Data Analysis (CAIDA) San Diego Supercomputer Center (SDSC) University of California, San Diego (UCSD) URL: https://www.caida.org/projects/as-core/ Visualization Thumbnail About the Visualization Visualization Techniques: (Technique1): Position of each AS is plotted in polar coordinates, position(radius, ) such that: Key Visualization Mappings: (Mapping1): Richer peering relationships are reflected by positions closer to the center of the graph. (Mapping2): represents the geographic longitude of the AS headquarters. Colored arcs at the perimeter distinguish longitudes of different continents.
