Building IP geolocation database from online used market articles
Hyunsu Mun, Youngseok Lee · 2017
An IP geolocation database provides location information for each IP address block. Though free and commercial IP geolocation databases are available, their accuracy and coverage are not clearly known for non US countries. In this paper, for the wider and more accurate IP geolocation service in Korea, we present a crowd-sourcing IP geolocation database build-up method by analyzing messages of an online used market, Ruliweb that reveals IP addresses and location information. From 195,937 posts on the Ruliweb website over 29 months, we can construct a Korean IP geolocation database that achieves the district-level granularity and outperforms commercial services in the accuracy. Though every online website does not provide IP address information, our crowd-sourcing methodology is useful for IP geolocation database management in Internet or mobile services.
