Get Started With IP2Location Java Module
Dependencies
This library requires IP2Location BIN database to function. You may download the BIN database at
IP2Location LITE BIN Data (Free): https://lite.ip2location.com
IP2Location Commercial BIN Data (Comprehensive): https://www.ip2location.com
IPv4 BIN vs IPv6 BIN
Use the IPv4 BIN file if you just need to query IPv4 addresses.
Use the IPv6 BIN file if you need to query BOTH IPv4 and IPv6 addresses.
Compilation
javac com/ip2location/*.java
jar cf ip2location.jar com/ip2location/*.class
Sample Codes
Query geolocation information from BIN database
You can query the geolocation information from the IP2Location BIN database as below:
import com.ip2location.*;
// import java.nio.file.*;
public class Main
{
public Main()
{
}
public static void main(String[] args)
{
try
{
String ip = "8.8.8.8";
String binfile = "/usr/data/IP-COUNTRY-REGION-CITY-LATITUDE-LONGITUDE-ZIPCODE-TIMEZONE-ISP-DOMAIN-NETSPEED-AREACODE-WEATHER-MOBILE-ELEVATION-USAGETYPE-ADDRESSTYPE-CATEGORY-DISTRICT-ASN.BIN";
IP2Location loc = new IP2Location();
// 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();
}
}
}
Processing IP address using IP Tools class
You can manupulate IP address, IP number and CIDR as below:
import com.ip2location.*;
import java.math.BigInteger;
import java.util.*;
public class Main
{
public Main()
{
}
public static void main(String[] args)
{
try
{
IPTools tools = new IPTools();
System.out.println(tools.IsIPv4("60.54.166.38"));
System.out.println(tools.IsIPv6("2600:1f18:45b0:5b00:f5d8:4183:7710:ceec"));
System.out.println(tools.IPv4ToDecimal("60.54.166.38"));
System.out.println(tools.IPv6ToDecimal("2600:118:450:5b00:f5d8:4183:7710:ceec"));
System.out.println(tools.DecimalToIPv4(new BigInteger("1010214438")));
System.out.println(tools.DecimalToIPv6(new BigInteger("50510686025047391022278667396705210092")));
System.out.println(tools.CompressIPv6("0000:0000:0000:0035:0000:FFFF:0000:0000"));
System.out.println(tools.ExpandIPv6("500:6001:FE:35:0:FFFF::"));
List<String> stuff = tools.IPv4ToCIDR("10.0.0.0", "10.10.2.255");
stuff.forEach(System.out::println);
List<String> stuff2 = tools.IPv6ToCIDR("2001:4860:4860:0000:0000:0000:0000:8888", "2001:4860:4860:0000:eeee:ffff:ffff:ffff");
stuff2.forEach(System.out::println);
String[] stuff3 = tools.CIDRToIPv4("10.123.80.0/12");
System.out.println(stuff3[0]);
System.out.println(stuff3[1]);
String[] stuff4 = tools.CIDRToIPv6("2002:1234::abcd:ffff:c0a8:101/62");
System.out.println(stuff4[0]);
System.out.println(stuff4[1]);
}
catch(Exception e)
{
System.out.println(e);
e.printStackTrace(System.out);
}
}
}
List down country information
You can query country information for a country from IP2Location Country Information CSV file as below:
import com.ip2location.*;
import java.util.*;
public class Main
{
public Main()
{
}
public static void main(String[] args)
{
try
{
Country cc = new Country("/usr/data/IP2LOCATION-COUNTRY-INFORMATION.CSV");
Map<String, String> ccresult = cc.GetCountryInfo("US");
System.out.println(ccresult.toString());
List <Map<String, String>> ccresults = cc.GetCountryInfo();
System.out.println(ccresults.toString());
}
catch(Exception e)
{
System.out.println(e);
e.printStackTrace(System.out);
}
}
}
List down region information
You can get the region code by country code and region name from IP2Location ISO 3166-2 Subdivision Code CSV file as below:
import com.ip2location.*;
public class Main
{
public Main()
{
}
public static void main(String[] args)
{
try
{
Region reg = new Region("/usr/data/IP2LOCATION-ISO3166-2.CSV");
String regionCode = reg.GetRegionCode("US", "Nevada");
System.out.println(regionCode);
}
catch(Exception e)
{
System.out.println(e);
e.printStackTrace(System.out);
}
}
}
