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

Programação Java
#1

[code]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>");    
	}    
}

}[/code]

cria uma função com este código e pede pra ser executado por threads
