Cloudflare has a list of IP addresses that it operates on (https://www.cloudflare.com/ips). I would like to whitelist these within my Wordfence settings. However they have them listed in a different format than the example shown in Wordfence.
Would something like this:
199.27.128.0/21
Need to be changed to this instead?
199.27.128.[0-21]
Also I am unclear on the proper format for the IPv6 addresses listed, which are in a different format, such as this:
2400:cb00::/32
