    public static void main(String[] args) {
        getAllDNS();
        getDNS();

    private static void getAllDNS() {
        try {
            InetAddress[] address = InetAddress.getAllByName("www.google.com");
            for (int i = 0; i < address.length; i++) {
                System.out.println(address[i].getHostAddress());

            System.out.println(address.getHostAddress());
        } catch (Exception e) {
            System.out.println(e.toString());
