I have an ip range, where my websites use cloudflare, I will for example a specific IP:
At that IP, we can directly access http://126.96.36.199 at port 80
But if using an arbitrary domain that is proxy via cloudflare intermediary to 188.8.131.52, we cannot access
(You can point any subdomain to my IP to check)
What is the problem? Problems from my ISP or Cloudflare network that has limited range of networks?
