How does the hosting checker work?

It resolves the domain to an IP address via DNS, then looks up the IP's ASN (Autonomous System Number) and organization data. The organization name identifies the hosting provider or data center.

Why does my site show Cloudflare instead of my host?

If your domain uses Cloudflare (or another CDN) as a proxy, the CDN's IP will be returned rather than your origin server's IP. This is expected behavior and protects your origin server.

Can I find out if a competitor uses AWS or Google Cloud?

Yes. The tool identifies the hosting provider from the ASN. If the domain resolves to AWS, Google Cloud, Azure, or another major provider, it will be detected and labeled.

Is the result always accurate?

For most sites, yes. Sites with Anycast IPs (Cloudflare, Google) or multi-cloud setups may show the CDN or load balancer rather than the backend host.

Why does a site show Cloudflare instead of the actual host?

Sites using Cloudflare as a CDN and proxy hide their origin server IP. Cloudflare's IP ranges are shown instead of the actual host. To find the origin, check DNS history tools or look for non-proxied subdomains.

Is this the same as a WHOIS lookup?

No. WHOIS shows domain registration data. This tool detects the IP hosting provider by cross-referencing IP address ranges with known cloud and hosting provider databases.
