Who is hosting this website?
Enter any domain to see which company hosts it — and the evidence behind the answer: fingerprint headers, the IP's network, and the nameservers. Plus the CDN, DNS provider, platform, and how fast the server answers.

What this measures
This checker answers "who is hosting this website?" from three independent signals: fingerprint headers that managed hosts stamp on every response (Kinsta, WP Engine, Hostinger, Cloudways, SiteGround and others), the network (ASN) that owns the server's IP address, and the domain's nameservers. It names the host with a confidence level and the exact evidence, plus the CDN in front, where DNS is managed, the platform (WordPress, Shopify, Webflow…), and how fast the server answered.
How to read your result
- Confirmed
- A host-specific fingerprint was found — a response header only that host sends, or an IP inside the host's own network. This is as certain as an outside check gets.
- Likely
- The signals point one way but none is decisive on its own — for example, a shared host's default nameservers on a site whose IP is hidden behind a CDN. Usually right, occasionally a site that moved its hosting but kept the old DNS.
- Hidden behind a CDN
- Cloudflare and similar proxies replace the server's IP with their own, so the network lookup only sees the CDN. If no header or nameserver gives the host away, the origin is genuinely hidden — that is the proxy doing its job.
- Cloud networks (AWS, Google Cloud, DigitalOcean…)
- When the IP belongs to a cloud provider's network, that is the only layer the lookup can see: the site may be self-managed there or run through a managed platform built on that cloud (Cloudways, Kinsta and SiteGround all are). A matching header names the managed layer when one is present.
- Server response time
- The time the server took to send its first byte on one cold request. Under 300 ms is good; over 800 ms means visitors wait on the server before anything renders — the part of speed the hosting controls.
Common causes & fixes
- You want to know where a site is hosted
- The headline answer plus the evidence list is the whole story. If it shows a CDN with the origin hidden, the site owner has deliberately masked the server — no public lookup can see past it.
- Your own site responds slowly
- Check whether a CDN is in front and whether the platform is cache-friendly, then run the TTFB test to see which phase is slow. A dominant server-wait phase points at the hosting plan or application, not the network.
- You're moving to a new host
- Note where DNS is managed: if it is your old host's nameservers, your DNS records move with the switch or must be recreated first. Lower the TTL before migrating so the change is visible within minutes.
- The result names the wrong company
- DNS and hosting can live at different providers, and resellers run on other companies' networks. Trust header-based (confirmed) results over nameserver hints, and treat cloud-network results as the infrastructure layer.
Frequently asked questions
How do I find out who hosts a website?
Enter the domain above. The checker looks up the IP address and the network that owns it, reads the response headers for host-specific fingerprints, and checks the domain's nameservers — then names the host along with the evidence for it.
Why does it say Cloudflare instead of the real host?
Cloudflare is a reverse proxy: visitors connect to Cloudflare's servers, which fetch the page from the real host. Its IP is all the outside world sees. The checker still identifies the host whenever a fingerprint header passes through the proxy.
Is a hosting lookup the same as a WHOIS lookup?
No. WHOIS shows who registered the domain name and at which registrar. The registrar is often a different company from the host — a domain bought at one company can point to a server anywhere.
Can I tell if a site uses WordPress?
Often, yes. The platform line shows WordPress when the server advertises the WordPress REST API in its headers or runs on a WordPress-only host, and names hosted platforms like Shopify, Squarespace, Wix and Webflow from their headers.
