I could convert the IP address to long format using the above logic, can any one tell how can I convert the long format back to IP address. I did search for the API I didn't get any. Is there any API which does it in Rails or any logic to which can do it like above(Equivalent APIs for long2ip and ip2long PHP built in Rails).
