Java find location using Ip Address
By：Roy.LiuLast updated：2019-08-18
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).
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]
