How can I block traffic FROM Amazon Technologies

[the one]

I am aware that Amazon now make available a complete list of their IP address blocks in JSON format here https://ip-ranges.amazonaws.com/ip-ranges.json


I have been told that you can use that to create rules to block all of those addresses.Now i am not really any good at this so this is my question.

What would i do with that would i copy it and add it in my CSF in WHM and if so can someone tell me where i put that or how do i create the rules block.

Many thanks.
