    Default Testing whether a list of URLs are active or not in java?

    I am trying to test a list of ip addresses in a local network. Currently the way I do it is by passing each ip through the following method:

    public static void testURL(String strUrl) throws Exception {
    try {
    URL url = new URL(strUrl);
    HttpURLConnection urlConn = (HttpURLConnection) url.openConnection();
    assertEquals(HttpURLConnection.HTTP_OK, urlConn.getResponseCode());
    } catch (IOException e) {
    System.err.println("Error creating HTTP connection");
    throw e;

    since i m going from 0 to 255, the whole process takes like an hour to finish, so I was wondering is there a way to check, which is faster than that?

    You could use a Socket with a timeout set.

    As explained here - java - can i speed up the scanning port process? - Stack Overflow
