CDN detection
Inspect DNS and public response headers for possible CDN providers.
How it works & common questions
How is a CDN identified?
Known provider patterns in CNAME/NS records and public HTTP headers are shown as evidence. Nameservers identify DNS hosting, not necessarily CDN traffic.
Does no match mean no CDN?
No. Providers can hide headers or use unrecognized domains. This tool offers evidence for review, not definitive attribution or exhaustive detection.
