        int ipAddress = wifiManager.getConnectionInfo().getIpAddress();

        // Convert little-endian to big-endianif needed
        if (ByteOrder.nativeOrder().equals(ByteOrder.LITTLE_ENDIAN)) {
            ipAddress = Integer.reverseBytes(ipAddress);
        }/*w  ww.j  av  a  2 s .  c o  m*/

        byte[] ipByteArray = BigInteger.valueOf(ipAddress).toByteArray();

        String ipAddressString;
        try {
            ipAddressString = InetAddress.getByAddress(ipByteArray)
                    .getHostAddress();
