java.net unable to connect to URL

I am trying to connect to a url using java.net to connect to a url but it keeps giving me an UnknownHostException: www.yahoo.com. I have tried everything. The firewall is not blocking java, i am able to ping the website from the computer running the code. I also tested with adding a line for proxy's to allow for the connection but that did not work either. I tried some other websites hosted on my servers as well but with no luck.

import java.net.*;
import java.io.*;

public class URLconnectionReader {
    public static void main(String[] args) throws Exception {
        Proxy proxy = new Proxy(Proxy.Type.HTTP, new InetSocketAddress("77.95.208.230", 8080));
        URL yahoo = new URL("http://www.yahoo.com/");
        URLConnection yc = yahoo.openConnection();
        BufferedReader in = new BufferedReader(
                                new InputStreamReader(
                                yc.getInputStream()));
        String inputLine;

        while ((inputLine = in.readLine()) != null) 
            System.out.println(inputLine);
        in.close();
    }
}
