Provider and edge hints
Hosting Checker
Combine website response markers, reverse DNS, nameservers, ASN hints, and RDAP context to infer likely hosting or edge providers with explainable evidence.
This page avoids overclaiming. It only surfaces providers and platforms when there are explainable signs in the response, naming, or public ownership data.
ASN names, IP RDAP records, nameservers, and reverse DNS can suggest whether the site sits behind a major host, CDN, or edge provider.
Headers and HTML markers often reveal whether the site is using a builder or platform like Shopify, Wix, or WordPress.
Each detection comes with evidence so you can decide whether it looks convincing or should stay in the “possible hint” bucket.

What this tool checks
Provider hints from ownership data
ASN names, IP RDAP records, nameservers, and reverse DNS can suggest whether the site sits behind a major host, CDN, or edge provider.
Platform markers in the response
Headers and HTML markers often reveal whether the site is using a builder or platform like Shopify, Wix, or WordPress.
Explainable confidence
Each detection comes with evidence so you can decide whether it looks convincing or should stay in the “possible hint” bucket.
02
How to use it
Run the check against the live public URL you care about, not a guessed origin host.
Read the evidence for the top provider before accepting it as final truth; multiple providers can appear in the same stack.

03
How to read the result
Edge is not always origin hosting
Cloudflare or another CDN can appear in front of an origin that lives on an entirely different provider.
ASN hints are useful but imperfect
A network owner name can suggest the platform, but modern stacks frequently mix DNS providers, CDNs, and origin hosts.
Unknown is a valid answer
When the evidence is weak, the tool should say unknown rather than invent a confident provider label.

Hosting Checker FAQ
Can one site show more than one provider?
Yes. DNS, CDN, builder, and origin hosting can all be different layers in the same public website stack.
Why is Cloudflare common in results?
Because Cloudflare often appears in nameservers, edge headers, and certificate issuance paths even when the true origin host is somewhere else.
What if the tool says unknown?
That usually means the public response did not expose enough trustworthy evidence to name a provider without overclaiming.
