Passive\ngeolocation relies on operators providing geolocation information, while active\ngeolocation tries to calculate the location of an IP address automatically.<\/p>\n\n\n\n<p>Candela noted that there are various\nsources for passive geolocation, including geolocation information inserted in\nhostnames by the operators, the DNS LOC field, RIR databases (location of the\ncompany to which an IP prefix has been assigned), and crowsdourced data.\nHowever, he explained that these sources are either non-standard (and therefore\ndifficult to use in an automated way) or rarely utilized. \u201cAdditionally, being\nmanual, they are prone to provide stale information,\u201d he added.<\/p>\n\n\n\n<p>Candela placed special emphasis on active\ngeolocation tools such as <a href=\"https:\/\/www.lacnic.net\/3106\/2\/lacnic\/ip-geolocation\">Geofeeds<\/a>, a\npromising format for self-publishing IP geolocation information. \u201cThis can be\nused both to publish geolocation information about our own prefixes as well as\nto correct a group of prefixes by sending such files to geolocation providers.\u201d<\/p>\n\n\n\n<p>Active measurements use latency\nmeasurements from devices of known position to estimate where the target is\nlocated (latency is converted into distance).<\/p>\n\n\n\n<p>In this sense, he observed that RIPE NCC\nhas probably the only platform performing active geolocation on a large-scale,\nwith a precision of 80.3% at city level. LACNIC has also developed a <a href=\"https:\/\/www.lacnic.net\/3106\/2\/lacnic\/ip-geolocation\">Geofeeds<\/a>\ngeolocation tool which is in its expansion phase.<\/p>\n\n\n\n<p>During the\nwebinar, Candela presented several tools used to correct geolocation\ninformation and which are currently available to providers. He also provided a\nlist of contacts\/APIs\/forms that can be used to correct geolocation\ninformation. <\/p>\n\n\n\n<p>Click<a href=\"https:\/\/www.lacnic.net\/4689\/2\/lacnic\/current-status-of-ip-geolocation\"> here<\/a> to watch\nthe webinar<\/p>\n","protected":false},"excerpt":{"rendered":"<p>During the webinar titled \u201cCurrent Status of IP Geolocation\u201d organized by LACNIC, Italian expert Massimo Candela stressed the importance of having reliable information on where Internet addresses are being used.
