Internet Mapping Project

The Internet Mapping Project[1][2] was started by William Cheswick and Hal Burch at Bell Labs in 1997.

The technology is now used by Lumeta, a spinoff of Bell Labs, to map corporate and government networks.

The data allows for both a snapshot and view over time of the routed infrastructure of a particular geographical area, company, organization, etc.

According to Cheswick, a main goal of the project was to collect the data over time, and make a time-lapse movie of the growth of the Internet.
