CAIDA plans to conduct a comparison of geolcocation tools for determining the location of Internet Protocal (IP) address (and other identifiers) in the summer of 2010. At this time we wish to receive feedback from interested parties on input to the comparison survey, whether they wish to participate and in what capacity. * What is your primary interest in geolocation services? Legal, academic, content localization, disaster preparedness, regulation, ... * Can you provide ground truth geolocation information for your organization? * Do you have suggested metrics, questions, or tests to include in the comparisons? * If you provide a geolocation service, under what conditions would you be willing to participate? * If you use a Geolocation service(s), which do you use and in what way? * Which companies do you consider to be the primary providers of geolocation services at this time? Please send any comments to: geocompare-info@caida.org Details can be found: http://www.caida.org/projects/cybersecurity/geolocation/ -- "Be always at war with your vices, at peace with your neighbors, and let each new year find you a better man." - Benjamin Franklin
