Can I whitelist a range of IP addresses and domains used by Janrain?

We use Amazon Web Services, and while they publish quite an extensive list of IP ranges for the different regions (see http://docs.aws.amazon.com/general/latest/gr/aws-ip-ranges.html#aws-ip-download) these can change at any time.

We recommend that you do not hard code any of their IP ranges, as they will change at some point in the future. Instead, we recommend that customers whitelist domains such as rpxnow.com
