This site or product includes IP2Location LITE data available from http://www.ip2location.com

IP2Location for Java

The repository code is based on ip2location repository.

Example: https://www.renfei.net/kitbox/ip

Download

The update cycle of database bin file is once a month.

Database bin file:

Or download the zip file in the warehouse and decompress it by yourself.

Installing in maven

<dependency>
    <groupId>net.renfei</groupId>
    <artifactId>ip2location</artifactId>
    <version>1.2.1</version>
</dependency>

Compared with the official client, I removed the ip2locationweb service and the dependency on other libraries.

Usage

import net.renfei.ip2location.*;

public class Main {
    public Main() {
    }

    public static void main(String[] args) {
        IP2Location loc = new IP2Location();
        try {
            String ip = "8.8.8.8";
            String binfile = "/usr/data/IP2LOCATION-LITE-DB11.BIN";

            // this is to initialize with a BIN file
            loc.Open(binfile, true);

            // this is to initialize with a byte array
            // Path binpath = Paths.get(binfile);
            // byte[] binFileBytes = Files.readAllBytes(binpath);
            // loc.Open(binFileBytes);

            IPResult rec = loc.IPQuery(ip);
            if ("OK".equals(rec.getStatus())) {
                System.out.println(rec);
            } else if ("EMPTY_IP_ADDRESS".equals(rec.getStatus())) {
                System.out.println("IP address cannot be blank.");
            } else if ("INVALID_IP_ADDRESS".equals(rec.getStatus())) {
                System.out.println("Invalid IP address.");
            } else if ("MISSING_FILE".equals(rec.getStatus())) {
                System.out.println("Invalid database path.");
            } else if ("IPV6_NOT_SUPPORTED".equals(rec.getStatus())) {
                System.out.println("This BIN does not contain IPv6 data.");
            } else {
                System.out.println("Unknown error." + rec.getStatus());
            }
            System.out.println("Java Component: " + rec.getVersion());
        } catch (Exception e) {
            System.out.println(e);
            e.printStackTrace(System.out);
        } finally {
            loc.Close();
        }
    }
}
