I'm using Clojure, but I can read Java, so this isn't a Clojure specific question. This doesn't even seem to be working from Java.

I'm trying to implement a bit of a 'ping' function using isReachable. The code I'm using is this:

(.isReachable (java.net.InetAddress/getByName "www.microsoft.com") 5000)

Translated to Java by a good friend of mine:

public class NetTest {
  public static void main (String[] args) throws Exception{
    String host = "acidrayne.net";
    InetAddress a = InetAddress.getByName(host);

    System.out.println(a.isReachable(10000));
  }
}

Both of these return false. I suppose I must be doin' it wrong, but Google research is telling me differently. I'm confuzzled!
