CDN / Hosting Fingerprinter

Identify the likely CDN, hosting provider, or edge/WAF in front of any domain using DNS, ASN, and header signals. Great for verification and research.


CDN / Hosting Fingerprinter

Introduction

This CDN / Hosting Fingerprinter identifies the likely CDN, hosting provider, or edge network behind a website. It’s built for SEOs, analysts, and engineers who need to understand where a site is hosted, which CDN serves it, and whether any reverse proxy or WAF is in front of it. Use it to research competitors, verify your own deployments, or troubleshoot performance and routing issues.

What is this tool?

When you enter a domain, the tool inspects DNS records, IP ranges/ASN, and response headers to infer the CDN or host. Common signals include CNAME patterns, known CDN anycast ranges, server headers, and WAF fingerprints. The output helps you see if a site uses Cloudflare, Fastly, Akamai, AWS CloudFront, a managed host, or a direct origin.

Why use this tool?

- Competitive research: See which CDN/host competitors rely on for performance or protection.
- Deployment verification: Confirm your site is actually served through the intended CDN/WAF after DNS changes.
- Performance planning: Understand edge presence and routing to decide on your own CDN strategy.
- Security posture check: Spot WAF/proxy layers that may affect testing or integration.
- Troubleshooting: Identify whether issues might be CDN-side, host-side, or at the origin.

How to use it

1) Enter the domain (e.g., example.com).
2) Click “Check.”
3) Review the detected CDN/host/ASN and any notable headers or CNAME clues.
4) If results differ from what you expect, review your DNS, proxy, and CDN settings.
5) Re-test after making DNS or CDN configuration changes to confirm they took effect.

Example

Input: example.com
Output: Likely CDN: Cloudflare; ASN: AS13335; Notes: “cf-ray” header detected
Interpretation: Traffic is served via Cloudflare’s edge with their WAF/proxy active.

FAQ

Do you store the domains I check?

No—lookups are used only to retrieve live signals and aren’t retained.

Why might detection be uncertain?

Some providers mask headers, share ranges, or sit behind multiple layers (proxy → CDN → origin). Results are “best guess” based on observed signals.

Does this expose my origin IP?

If the origin is already shielded by a CDN/WAF, this tool won’t bypass it. It reports likely edge/CDN/host info from public-facing signals.

How do I act on the result?

If it’s not the provider you intended, review DNS (CNAME/A/AAAA), ensure proxy/CDN is enabled, and confirm SSL/WAF settings. If migrating, wait for DNS/TTL propagation and retest.
