In Java, third-party libraries like GeoIP2 and ip2region can be used to retrieve the location based on an IP address.<\/p>\n

    \n
  1. Utilize the GeoIP2 library:<\/li>\n<\/ol>\n

    Firstly, you need to download the GeoIP2 Java library and then use it in your code to retrieve the location of an IP address.<\/p>\n

    import<\/span> com.maxmind.geoip2.DatabaseReader;\r\nimport<\/span> com.maxmind.geoip2.model.CityResponse;\r\nimport<\/span> java.io.File;\r\nimport<\/span> java.net.InetAddress;\r\n\r\npublic<\/span> class<\/span> IPUtil<\/span> {\r\n\r\n    public<\/span> static<\/span> void<\/span> main<\/span>(String[] args)<\/span> throws<\/span> Exception {\r\n        File<\/span> database<\/span> =<\/span> new<\/span> File<\/span>(\"\/path\/to\/GeoLite2-City.mmdb\"<\/span>);\r\n        DatabaseReader<\/span> reader<\/span> =<\/span> new<\/span> DatabaseReader<\/span>.Builder(database).build();\r\n\r\n        InetAddress<\/span> ipAddress<\/span> =<\/span> InetAddress.getByName(\"128.101.101.101\"<\/span>);\r\n        CityResponse<\/span> response<\/span> =<\/span> reader.city(ipAddress);\r\n\r\n        String<\/span> country<\/span> =<\/span> response.getCountry().getName();\r\n        String<\/span> city<\/span> =<\/span> response.getCity().getName();\r\n\r\n        System.out.println(\"Country: \"<\/span> + country);\r\n        System.out.println(\"City: \"<\/span> + city);\r\n    }\r\n}\r\n<\/code><\/pre>\n
      \n
    1. Utilize the ip2region library.<\/li>\n<\/ol>\n
      ip2region is a Java implementation of a pure IP database, which allows for fast retrieval of location information based on an IP address.<\/p>\n
      import<\/span> org.lionsoul.ip2region.*;\r\nimport<\/span> java.io.IOException;\r\n\r\npublic<\/span> class<\/span> IPUtil<\/span> {\r\n\r\n    public<\/span> static<\/span> void<\/span> main<\/span>(String[] args)<\/span> throws<\/span> DbMakerConfigException, IOException {\r\n        DbConfig<\/span> config<\/span> =<\/span> new<\/span> DbConfig<\/span>();\r\n        DbSearcher<\/span> searcher<\/span> =<\/span> new<\/span> DbSearcher<\/span>(config, \"\/path\/to\/ip2region.db\"<\/span>);\r\n\r\n        DataBlock<\/span> dataBlock<\/span> =<\/span> searcher.btreeSearch(\"128.101.101.101\"<\/span>);\r\n\r\n        String<\/span> region<\/span> =<\/span> dataBlock.getRegion();\r\n\r\n        System.out.println(\"Region: \"<\/span> + region);\r\n    }\r\n}\r\n<\/code><\/pre>\n
      The above are two commonly used methods to choose the appropriate tool for obtaining the geographical location of an IP address based on specific needs.<\/p>\n","protected":false},"excerpt":{"rendered":"
