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).

Get a free GeoLite free Databases – here
Get a GeoIP client Java APIs – here
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.mkyong.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]

ipgeolocation.io is another IP geolocation API service that sounds a good alternative to Maxmind geoip location service.
You can also use IP geolocation API Java SDK. In the following link, you will go through the basic steps to use IP Geolocation API Java SDK.

Use below class if you got error

public class ServerLocation {

public void setCountryCode(String countryCode) {
System.out.println(“CountryCode:”+countryCode);

}

public void setCountryName(String countryName) {
System.out.println(“CountryName:”+countryName);

}

public void setRegion(String region) {
System.out.println(“Region:”+region);

}

public void setRegionName(String regionNameByCode) {
System.out.println(“RegionName:”+regionNameByCode);

}

public void setCity(String city) {
System.out.println(“City:”+city);

}

public void setPostalCode(String postalCode) {
System.out.println(“PostalCode:”+postalCode);

}

public void setLatitude(String valueOf) {
System.out.println(“Latitude:”+valueOf);

}

public void setLongitude(String valueOf) {
