Hi,
Traffic from private IP addresses are automatically whitelisted. Here is a link with more info:

Thanks!

That’s actually not an answer to my question. I only used a private IP address as an example. I think a more specific way of asking is; Does the whitelist API function support addresses in a CIDR format (e.g. includes the “/” at the end such that you can add blocks without having to convert them to the arbitrary range format listed in the documentation?
