Cloudflare operates one of the world's largest anycast networks, spanning more than 300 cities globally. Its IP ranges are used for CDN edge delivery, DDoS protection, Zero Trust access, and DNS resolution. Web servers commonly allowlist these ranges so that real visitor IPs are preserved in logs when traffic arrives via Cloudflare's proxy.
