I was asked to post this publicly. This is something I wrote for one of my accounts to be able to search across all CMAs for an IP address. It's a really straight forward function. The script crawls your domains and creates a search function script that it executes which then searches each CMA for that IP and outputs it to a single file in JSON format.
Depending on feedback I could easily update this to make a CSV or other format. It also would be very easy to add an option to lookup by name to the script as well.
Since this is a search by IP it will also list objects like subnets, ranges, etc that the IP can be a part of as well as group membership.
Feedback always welcome!
