    try {
        Enumeration<NetworkInterface> networkInterfaceEnumeration = NetworkInterface.getNetworkInterfaces();
        while (networkInterfaceEnumeration.hasMoreElements()) {
            NetworkInterface networkInterface = networkInterfaceEnumeration.nextElement();
            Enumeration<InetAddress> inetAddressEnumeration = networkInterface.getInetAddresses();
            while (inetAddressEnumeration.hasMoreElements()) {
                InetAddress inetAddress = inetAddressEnumeration.nextElement();
                if (!inetAddress.isLoopbackAddress()&&!inetAddress.isLinkLocalAddress()&&inetAddress.isSiteLocalAddress()) {
                    IPStringBuilder.append(inetAddress.getHostAddress().toString()+"\n");
                }
            }
        }
    }catch (SocketException ex) {
    }
    IP = IPStringBuilder.toString();
    return IP;
