How Cloudflare WAF block incoming requests

I have a question regarding the Cloudflare WAF on how it is handling and blocking an incoming request.

If my main site traffic goes through “Akamai”, some of my specific subdomains and subfolders will be redirected through Cloudflare.

So my question is if I enable the WAF on Cloudflare end and if for some reason WAF detects/block some requests that are proxied through Akamai, is it gonna block all Akamai’s IPs, or just a specific IP coming from client?
