Filter IPs coming from AWS

Question

I have a list of IPs and I want to filter out the IPs that come from AWS. Fortunately, AWS publishes a list of their IPs. That list is in a JSON format, so I converted it to a CSV. I then filtered my IP addresses using my_ip = my_ip[~my_ip['col'].isin(amazon_ips['col'])].

Unfortunately, I think that the list is for ranges of IPs, rather than actually containing each IP that an AWS request could have come from. How can I correct for this?

please share json structure of the aws ips you are storing. Without that no one will be able to guesswhat you are trying to achieve — Moinuddin Quadri, Sep 13 '16 at 21:03
@MoinuddinQuadri I included a link to the JSON in the original post. Here it is again https://ip-ranges.amazonaws.com/ip-ranges.json — Danny David Leybzon, Sep 13 '16 at 21:12

The list you are getting contains IP Ranges using CIDR Notation.

You could programmatically determine the individual IP addresses from a CIDR Block, if required: Python 3: create a list of possible ip addresses from a CIDR notation
