Counted across 892 sites checked with this tool, of which 615 could be attributed to a provider. The rest sit behind a proxy such as Cloudflare, which hides the origin server. A site counts once however often it was checked, so this reflects the sites people look up, not the web as a whole.
What the hosting checker tells you
Who hosts the site
The hosting company behind the domain, identified from response headers, host-installed plugins, reverse DNS and the nameservers — whichever gives a straight answer. Every result says which signal named it.
What it runs on
The network that owns the IP address: Google Cloud, AWS, Hetzner, DigitalOcean and the rest. Managed hosts rent from these, so the provider and the infrastructure are shown as two separate lines.
IP, DNS and CDN
IP address and its location, reverse DNS, the nameservers running the domain, and the CDN in front of it when there is one.
The WordPress stack
If the site runs WordPress, the same check also reports its theme, plugins, WordPress version, web server and PHP version.
How it works
- Resolve the domain to its IP address and look up which network owns it, along with its location.
- Read the DNS and the response: reverse DNS, the nameservers running the domain, and the headers and host plugins the server hands back.
- Name the provider from the strongest signal available, and say which one it was — or say the origin is hidden when the site sits behind a proxy.
Results are cached for 24 hours per site. Only public information is read.
Frequently asked questions
How does a hosting checker know who hosts a website?
A domain resolves to an IP address, and that address belongs to a network with a known owner. On top of that, hosts leave traces: their own response headers, must-use plugins they install, reverse DNS names like server11.example-host.com, and their nameservers. This tool reads all four and tells you which one produced the answer.
Why does it say the host is hidden behind Cloudflare?
When a site is proxied through Cloudflare (or Fastly, Akamai, Sucuri), the IP you can see belongs to that network, not to the hosting company. The origin server is deliberately hidden, so naming a host would be a guess. In those cases the tool says so instead, and still reports anything the response headers give away.
What is the difference between the hosting provider and the infrastructure?
The provider is who you pay and who supports you. The infrastructure is whose hardware it runs on. Kinsta and SiteGround both run on Google Cloud, WP Engine uses Google Cloud and AWS, and plenty of smaller hosts rent from Hetzner or OVH. Saying only "Google Cloud" would be true and useless, so both lines are shown.
Is the hosting checker accurate?
For sites that are not proxied, the IP owner and the DNS records are facts rather than guesses. The provider name on top of them is an inference, which is why each result names the signal it came from. Fingerprints in the response headers are the strongest; a network owner alone is the weakest.
Does it work for sites that are not WordPress?
Yes. The hosting, IP, DNS and CDN details come from the network and work for any website. The theme and plugin sections only appear when the site actually runs WordPress.
Is it free, and does it store the sites I check?
It is free and needs no account. Each check is saved so the tool can show which hosts are most common and how many sites have been checked; only the public home page is read, exactly as a visitor would.
