CAIDA's Geolocation Tools Comparison

This page describes CAIDA's plans to conduct a comparison survey of geolocation tools for determining the location of an Internet Protocol (IP) address (and other identifiers) and to evaluate the accuracy and reliability of such tools. Through this process, we intend to increase situational awareness of Internet topology structure, behavior, and vulnerabilities. This project receives support from (N66001-08-C-2029) Cybersecurity: Leveraging the Science and Technology of Internet Mapping for Homeland Security

Background

Governments, researchers, and commercial entities all share interest in mapping Internet resources to physical locations. Governments use this data to prepare and plan for adverse events as well as to tax and regulate. Academics use this data to more accurately depict how the Internet works and how people use it. Commercial interests might use the data to provide better localized services and targeted pricing.

These interests call for geolocation services that provide a an accurate mapping from the virtual world of the Internet to real physical locations. In the late 1990s, CAIDA developed a geolocation service, NetGeo, primarily to support its own research efforts. Although the tool received wide interest and usage from global users, we decommissioned the service in 2003 for lack of resources. Over time, these have been superseded by a mixture of commercial and volunteer efforts. Currently, CAIDA uses Digital Envoy's NetAcuity (tm) service under a no-cost, academic licensing agreement to support our geolocation needs.

CAIDA's Geolocation Tools Comparison Survey

As part of a current Internet mapping project, funded by DHS Cybersecurity project, we will conduct a rigorous comparison of various geolocation services, in terms of features, methodologies, and accuracy of output, to the extent we can validate.

Request for Feedback

We are interested in public feedback on the general state of geolocations and our evalution criteria.
If you can provide answers to the below questions, additional questions we should be asking, or any other feedback, please send them to geocompare-info@caida.org.

General Information Questions

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?

Geolocation Service Evaluation Criteria

What geographic granularity does it provide?
Continent, country, state/prefecture, city, zip code.
What Internet identifier granularity does it support?
Internet Protocol (IP) address, network prefix, Autonomous System (AS).
Does the accuracy of the results vary by geographic region or by type of network?
With what frequency does a service update its database?
How many queries per second can clients execute?
