How to block an IP address/country in Cloudflare.

[HostSailor.]

If your domain is using Cloudflare nameservers and you are seeing an IP is attacking your domain/server with a DDoS attack, you can simply block the IP or the entire IP range or even the country itself from the Cloudflare panel. Usually, Cloudflare will rate-limit the connections based on the settings, but sometimes it is not good enough to prevent it from attacking the site and making it inaccessible.​
