            Enumeration networkInterfaces = NetworkInterface.getNetworkInterfaces();
            while (networkInterfaces.hasMoreElements()) {
                NetworkInterface ni = (NetworkInterface) networkInterfaces.nextElement();
                Enumeration nias = ni.getInetAddresses();
                while (nias.hasMoreElements()) {
                    InetAddress ia = (InetAddress) nias.nextElement();
                    if (!ia.isLinkLocalAddress() && !ia.isLoopbackAddress() && ia instanceof Inet4Address) {
                        hostIP=ia.getHostAddress();
                    }
                }
            }
        } catch (SocketException e) {
