rTraceroute Database
The rTraceroute tool uses a database called IP_GEOLOC. The latter consists of two tables
labeled IP and MAPS. The IP table gives the correspondence between an IP address, latitude, longitude, ISO 3166 code
and AS number of a country. While the MAPS table gives the mapping between an IP address, the coordinates
(mapx, mapy) in the output image and the ISO 3166 code of a country.
