Questions about Cloudflare Rate Limiting

I’m considering using Cloudflare Rate Limiting for my service, but I have a few questions about how it works.

  • How are IPv6 clients treated? Is a /64 subnet treated as a single IP?
  • Does Rate Limiting solely use IPs to identify a client or is some kind of fingerprinting used as well?

Thanks a lot in advance! :slightly_smiling_face:
