I'm not sure where the image you've posted has come from but the evidence points to the site using a dated Geo IP list from Maxmind. The 'registered_country_geoname_id' field is still set to the states but this shouldn't be used for geo-location as it's perfectly feasible to register a block of IP's in one country for use in another. So both lists show the 146.200.0.0/16 block to be located in the UK. The geoip.jar file is the actual code used to access the database/file which is GeoIPLite. command line option : -J or -json-pretty. Network_start_ip,network_prefix_length,geoname_id,registered_country_geoname_id,represented_country_geoname_id,postal_code,latitude,longitude,is_anonymous_proxy,is_satellite_provider CountryLookupTest.java These are written by a company called maxmind and are used to work out what country a person comes from based on their IP address. This tool uses a database to use the (pre-fetched) GeoIP2 data from. This is somewhat irrelevant though, because I've extracted the necessary info form the GeoLite2 City list and get this: It looks like they have a few different Geo IP lists.Ī a lookup on their site uses their 'GeoIP2 Precision' list, however the image you've shared suggests it's their free ' GeoLite2 City' list that's in use.
