About this network

A secondary Cloudflare Autonomous System (CLOUDFLARE). Cloudflare operates a large global CDN, DDoS-mitigation, and edge-compute network fronting millions of websites and APIs.

What it's used for

• Reverse-proxy, caching, WAF, and DNS in front of customer origins; edge compute via Workers.

Notable

• An IP here is a Cloudflare edge, not the customer origin behind it — the real backend could be anywhere.
• Cloudflare's primary ASN is AS13335; this number carries additional prefixes for the same anycast network.

Interesting

• Cloudflare's edge is anycast, so the same IP is served from whichever of its hundreds of cities is nearest the requester.
