Java – Find Location Using Ip Address

In this example, we show you how to find a location (country, city, latitude, longitude) using an IP address.

1. GeoLite Database

The MaxMind provides a free GeoLite database (IP Address to Location).

1. Get a free GeoLite free Databases – here
2. Get a GeoIP client Java APIs – here
3. Start code it.

2. GeoLite Java Example

An example to use GeoIP client Java APIs to find a location using IP address.

GetLocationExample.java

package com.analysis.location;
 
import java.io.File;
import java.io.IOException;
import com.maxmind.geoip.Location;
import com.maxmind.geoip.LookupService;
import com.maxmind.geoip.regionName;
import com.mkyong.analysis.location.mode.ServerLocation;
 
public class GetLocationExample {
 
  public static void main(String[] args) {
 GetLocationExample obj = new GetLocationExample();
 ServerLocation location = obj.getLocation("206.190.36.45");
 System.out.println(location);
  }
 
  public ServerLocation getLocation(String ipAddress) {
 
 File file = new File(
     "C:\\resources\\location\\GeoLiteCity.dat");
 return getLocation(ipAddress, file);
 
  }
 
  public ServerLocation getLocation(String ipAddress, File file) {
 
 ServerLocation serverLocation = null;
 
 try {
 
 serverLocation = new ServerLocation();
 
 LookupService lookup = new LookupService(file,LookupService.GEOIP_MEMORY_CACHE);
 Location locationServices = lookup.getLocation(ipAddress);
 
 serverLocation.setCountryCode(locationServices.countryCode);
 serverLocation.setCountryName(locationServices.countryName);
 serverLocation.setRegion(locationServices.region);
 serverLocation.setRegionName(regionName.regionNameByCode(
             locationServices.countryCode, locationServices.region));
 serverLocation.setCity(locationServices.city);
 serverLocation.setPostalCode(locationServices.postalCode);
 serverLocation.setLatitude(String.valueOf(locationServices.latitude));
 serverLocation.setLongitude(String.valueOf(locationServices.longitude));
 
 } catch (IOException e) {
  System.err.println(e.getMessage());
 }
 
 return serverLocation;
 
  }
}

Output

ServerLocation [countryCode=US, countryName=United States, region=CA, 
 regionName=California, city=Sunnyvale, postalCode=94089, 
 latitude=37.424896, longitude=-122.0074]
