About this network

One of Cloudflare's Autonomous Systems, registered to Cloudflare London, LLC and carrying the handle CLOUDFLARESPECTRUM. It rides on Cloudflare's global edge but is used for Spectrum and BYOIP (Bring Your Own IP) customer traffic rather than the core CDN address pool.

What it's used for

• Announcing customer-brought IP ranges and Spectrum (generic TCP/UDP proxy) services that sit behind Cloudflare's edge network.

Notable

• Cloudflare's primary network is AS13335, which this ASN peers from as an upstream. An IP here is on Cloudflare's edge but may front a specific customer's BYOIP ranges.
