You can view the list of Security Intelligence IP addresses from the CLI of the Defense Center. You'll want to issue the following commands after logging in:
1. sudo su
2. cd /var/sf/iprep_download
In this directory, there is a file called rep_dd.yaml. You can view this text file to find the UUID associated with each category, such as "attackers".
There should be a file in the /var/sf/iprep_download directory named for that UUID, for example 5a0b6d6b-e2c3-436f-b4a1-48248b330a26. You can view this file using the "less" command in order to see the IP addresses that are currently included for that particular category.
