import java.net.UnknownHostException;

public class IpAddressExample {
	public static void main(String[] args) {
		InetAddress ipAddress = null;
		try{
			ipAddress=InetAddress.getLocalHost();
		}catch (UnknownHostException exception){
			exception.printStackTrace();
		}
		System.out.println("IP Address : "+ipAddress.getHostAddress());
	}
}
