Convert IP Address range to CIDR and JSON Ouput utilities

Hi,

I need to write a utility to maintain a customer IP addresses in a custom Z-Table  and output interface file of IP address info in this Z-Table.

I am going to use FPM search UIBB for the maintain of IP Address.

I am looking for some code or logic to:

1) Convert IP Range (IP Start - IP End) into CIDR format

2) Output utility to write to a file in JSON format.

I search the net but all I found is the conversion tool.  I need to write the logic in ABAP unless someone can tell me how to call these tool from ABAP to input range and return list of IP Address in CIDR format.

For JSON output utilities, does SAP provide any method for output IP Range.

Any suggestion would be greatly appreciated.  Thanks
