How can I find out who is hosting a website?

Use ZaxisMedia's free Hosting Provider Checker: enter any domain to instantly see its hosting company, server IP address, and server location. No signup needed.

How do you detect a website's hosting provider?

The tool resolves the domain to its IP, looks up reverse DNS, and reads response headers (Server, cf-ray, x-powered-by and others). Distinctive signatures, like a cf-ray header for Cloudflare, identify the provider.

What do the confidence levels mean?

High confidence means a distinctive response-header signature was found. Medium confidence means the provider was inferred from reverse DNS. If neither exists, the tool honestly reports that it cannot identify the host.

Why can't you always identify the host?

Sites behind CDNs and proxies (like Cloudflare) hide the origin server by design, and some hosts strip identifying headers. In those cases the tool reports the CDN layer it can see.

Can I see the server's IP address?

Yes, the tool shows the resolved public IP and its reverse DNS name, which often reveals the data center or network owner.

Is checking a site's host legal?

Yes. Everything comes from public DNS records and standard HTTP responses, the same data any browser receives.

About the Hosting Provider Checker

The Hosting Provider Checker resolves any domain, inspects reverse DNS and response headers, and tells you who hosts the site: Cloudflare, AWS, Vercel, Netlify, DigitalOcean, Hetzner and more.

Unlike tools that guess, it reports honest confidence levels: high when header signatures prove it, medium when reverse DNS suggests it, and a clear unknown when the trail goes cold.

Where it helps most

Decisions where real hosting data beats review-site rankings.

Shop for hosting

Find five sites you admire that load fast and check where they live; clear patterns emerge quickly with real data.

Research competitors

When a rival migrates from shared hosting to a cloud provider, their sudden speed jump finally makes sense.

Confirm migrations

Site owners use it after a migration to confirm the domain actually points at the new host and not the old one.

Know the infrastructure

See whether the site sits on shared hosting, a VPS or cloud infrastructure, which matters more than the brand for performance.

Reading the result

Limits worth knowing before you trust the name.

Proxies hide origins

A site behind Cloudflare or another proxy shows the proxy's network, not the origin host, so pair this with a CDN check.

Resellers blur brands

Many small hosts rent from larger clouds, so the network owner might be AWS while the brand on the invoice is someone else entirely.

Stale DNS misleads

After a migration, stale DNS records can keep pointing at the old server's IP, so the checker reports the old host until propagation finishes.

Hosting Provider Checker: built for trust

Reports what the network data actually says, and flags when a proxy sits in front instead of guessing.

Hosting Provider Checker FAQs

How can I find out who hosts a website?

Resolve the domain to its IP address and look up the network owner. The checker does this automatically and cross-checks server fingerprints to name the hosting provider.

Why does a site on Cloudflare show Cloudflare as the host?

Can it tell shared hosting from cloud hosting?

My site just migrated. Why does it still show the old host?
