Queria saber como faço para pingar em dois ou mas ips diferente ao mesmo tempo

import java.net.InetAddress;    
import java.net.UnknownHostException;    
import java.awt.Graphics;
import java.io.IOException;   
public class TestePing {  


	public static void main(String[] args) {  
		
		if (args.length == 1) {    
			InetAddress address = null;    
			try {    
				address = InetAddress.getByName(args[0]);    
			} catch (UnknownHostException e) {    
				System.out.println("Cannot lookup host "+args[0]);    
				return;    
				
			}    
			try {    
				if (address.isReachable(5000)) {    
					long nanos = 0;    
					long millis = 0;    
					long iterations = 0;    
					while (true) {    
						iterations++;    
						try {    
							nanos = System.nanoTime();    
							address.isReachable(500); // this invocation is the offender    
							nanos = System.nanoTime()-nanos;    
						} catch (IOException e) {    
							System.out.println("Failed to reach host");    
						}  
						
						millis = Math.round(nanos/Math.pow(10,6));    
						System.out.println("Resposta do IP: "+address.getHostAddress()+" com de tempo="+millis+" ms");    
					
						try {    
							Thread.sleep(Math.max(0, 1000-millis));    
						} catch (InterruptedException e) {    
							break;    
						}    
					}    
					System.out.println("Iterations: "+iterations);    
				} else {    
					System.out.println("Host "+address.getHostName()+" is not reachable even once.");    
				}    
			} catch (IOException e) {    
				System.out.println("Network error.");    
			}    
		} else {    
			System.out.println("Usage: java isReachableTest <host>");    
		}    
	}
}
