Jak uzyskać ip oraz port adresu url w postaci "http://w

tak jak w temacie

Adres IP:

try{
       URL u = new URL("http://forum.java.sun.com/thread.jspa?threadID=688524");
       InetAddress i = InetAddress.getByName(u.getHost());
       System.out.println(i.getHostAddress());
}catch(UnknownHostException uhe){
        uhe.printStackTrace();
}catch(MalformedURLException mue){
        mue.printStackTrace();
}
