ANT Census Datasets

Data Sources

Our Internet Address Space maps use data from several sources. The primary source is the Internet Address Census and Surveys we've taken at USC since 2003.

In addition, our browsable maps include views that include whois data from the regional internet registries in the "organization" plane, and IP geolocation data from Software77's IPToCountry database.

High resolution images of our address space maps are available upon request. Please contact John Heidemann for details.

Our address space scans are available to researchers upon request from the authors or through PREDICT as dataset PREDICT ID USC/LANDER internet_address_survey_it15w-20061108.

Details about the methodology are in USC/ISI technical report ISI-TR-2007-640 and at http://www.isi.edu/ant/address.
