What is this ball of colors? It is the North American Internet, or more specifically a map of just about every router on the North American backbone, (there are 134,855 of them for those who are counting). The colors represent who each router is registered to. Red is Verizon; blue AT&T; yellow Qwest; green is major backbone players like Level 3 and Sprint Nextel; black is the entire cable industry put together; and gray is everyone else, from small telecommunications companies to large international players who only have a small presence in the U.S.

There are more interesting mappings of the Internet that include some of the work that the United States Government funded with CAIDA, and work by commercial entities like Renesys. You can view what we think is a better idea of how things are mapping out here. Note, at&t and SBC have not been considered as a single entity yet as they continue to utilize seperate ASN's.
