Find out who is hosting any website.
Type a website address. The checker follows where its name points, names the company that runs each server address, and recognizes the platform or CDN in front of it.

How the checker finds the host
A website's name points at one or more server addresses in DNS. Every address belongs to a network, and every network to a company. The checker follows that path: it resolves the name, reads who runs each address from FFraud's IP records, and recognizes the platform from the names and addresses platforms give their customers.
Hosting company
The company that runs the network the site's addresses belong to.
Platform
Shopify, Vercel, Netlify, GitHub Pages, Squarespace, WP Engine and others, recognized by the names and addresses they hand their customers.
CDN or proxy
Cloudflare, Akamai, Fastly and similar networks answer for a site from their own servers. When one stands in front, the server behind it stays hidden.
CNAME chain
The names the domain points through on the way to its addresses. They often name the platform outright.
Address and network
Each server address, the network it belongs to (its ASN), and roughly where it sits.
When the host hides behind a CDN
Many sites put a CDN or a security proxy in front of their server. Visitors reach the CDN, and the CDN fetches the pages from the real server out of sight. The checker names the CDN. The company behind it stays private by design: only the site's owner and the CDN can name it.
Why people look up a website's host
To report abuse: a phishing page or a fake shop comes down fastest when its host hears about it, and hosting companies run abuse desks for exactly that. To vet a shop before paying it, since a store that claims a famous brand but runs on a host the brand would never use deserves a second look. And to study a competitor's setup or plan a move to another host.
What the checker cannot see
It reads what DNS publishes, live, at the moment you ask. A site behind a CDN shows the CDN. A platform that runs on a cloud network shows both, the platform and the network that carries it. A site can move to another host at any time, and the next lookup shows the new one.
Questions people ask.
Type its address above. The checker resolves the name, names the company that runs each server address, and recognizes the platform or CDN in front of the site. Each address links to its full record on FFraud.
Not from the outside. Cloudflare answers for the site from its own servers, so every visitor, this checker included, sees Cloudflare's addresses. To reach the real host about a phishing page or a scam, report it to Cloudflare, which passes abuse reports on to the hosting provider.
Look up the host here, then open the address's record on FFraud: it shows the abuse contact the registry lists for that network, when there is one. Send the page's address, what it does and when you saw it. For a site behind a CDN, report it to the CDN.
No. The host runs the servers; the owner is whoever registered the domain and pays for the site. The domain's registration record names the owner, and most registrars hide that name behind a privacy service.
Not by itself: small sites everywhere run on shared hosting. A shop that claims a famous brand but sits on a host that brand would never use deserves a second look, and the website safety check tells you whether the domain is listed for phishing or scams.
Large sites spread their traffic across several servers, and many publish both IPv4 and IPv6 addresses. Each address is shown with the network it belongs to.
