CDN & Edge Network IP Ranges
Content delivery and edge networks — Cloudflare, Akamai, Fastly, Bunny, CacheFly, G-Core and QUIC.cloud.
One file, every CDN and edge network
13,879 ranges from 7 providers in a single download. Permalinks — they always return the latest data, so you can curl them from a cron job.

Two directions here. Inbound: if your site sits behind a CDN, requests should only ever reach your origin from these ranges — allowlist them at the origin firewall and drop everything else, so nobody bypasses the CDN by hitting your IP directly. Also make sure your logs read the forwarded client IP rather than the edge address, or every visitor will look like the same handful of hosts. Outbound: a request arriving from these ranges tells you which CDN fronted it, not who the visitor is.
