Who is hosting this website?
Four different companies can be involved in one website, and people mix them up constantly. The registrar sold you the domain. The DNS provider answers the question “where does this domain point?”. The host runs the server that actually serves the pages. The email provider handles mail. They can all be the same company, or four different ones — this tool reports each separately, so you know exactly who to call.
The CDN problem
Most “who is hosting this” tools do one thing: look up the domain's IP address and report who owns it. That works right up until the site uses a CDN — and a large share of the web now does. Behind Cloudflare, the IP belongs to Cloudflare no matter who runs the origin server, so those tools confidently answer “Cloudflare” and are simply wrong.
This one separates the two. If a CDN is in front, we say so, and then look for evidence the origin gives away regardless: response headers that only a particular host sets, DNS records the owner forgot to proxy, or a platform's own fingerprints in the page. When that evidence isn't there, we tell you the origin is hidden rather than naming the CDN and hoping you don't notice.
What to do with the answer
Usually people run this for one of three reasons: they inherited a site and nobody knows where it lives, they're sizing up a competitor's setup, or they're unhappy and working out what leaving would involve. If it's the third, the honest summary is that moving a site is mostly a DNS exercise and it can be done without downtime when it's sequenced properly.
Common questions
Why did it say the site is behind Cloudflare instead of naming the host?
Because that's the truth. When a site uses Cloudflare (or Fastly, or CloudFront), the address the internet sees belongs to the CDN, not to the server running the site. Tools that answer "Cloudflare" to "who hosts this" are reporting the doorman as the tenant. We look for evidence the origin leaks anyway — response headers only the real host sets, unproxied DNS records, the platform's own markup — and if none of it is there, we say so instead of guessing.
How accurate is this?
Every result shows its evidence and a confidence level, so you can judge it yourself. High confidence means the host identified itself — a header only it sets, reverse DNS on its own network, or platform markup in the page. Medium usually means reverse DNS says one thing but a CDN sits in the path. Low means we're inferring from nameservers alone, which is a hint, not proof.
Is the web host the same as the domain registrar?
Often, but not always — and they're different jobs. The registrar is who you bought the domain from; the host is whose server answers when someone visits. Plenty of people buy a domain one place, host somewhere else, and run email in a third. That's why this tool reports all of them separately.
What's the difference between the host and the platform?
The host is the company whose hardware runs the site. The platform is the software on top — WordPress, Shopify, Webflow. On a site builder they're the same company, which is the point of a site builder. On WordPress they're usually not: WordPress is free software that someone has to host somewhere.
Can the site owner see that I checked?
We request the homepage once, the same way any browser or search-engine crawler does, and read public DNS records. Nothing identifies you, and nothing is sent to the site owner.
Found out you're somewhere you'd rather not be? Squish-managed hosting includes the migration — we move the site, cut DNS over, and keep it patched, backed up, and monitored afterwards.
