Cloudflare maintains a large and constantly changing pool of IPv4 addresses. The primary range is 104.21.23.0/22. However, Cloudflare provides tools and documentation for identifying their current IP ranges. You can find the most up-to-date ranges on the Cloudflare website: https://www.cloudflare.com/ips/ and using the `dig` command with the `any` search option for `cloudflare.com` can show you their current IP addresses.
