Hosting checker FAQs

Enter the domain in the hosting checker above. It resolves the site's IP address, looks up the network owner, and identifies the hosting provider along with the server's location. Note that sites behind a CDN like Cloudflare will show the CDN's network rather than the origin host.
Yes — you can enter an IP address directly. The tool performs a reverse lookup on the IP's ASN and network registration to identify the provider operating that range, which usually reveals the hosting company or data center behind it.
When a site uses a CDN or proxy service, visitors connect to the CDN's edge servers, so the publicly detectable IP belongs to the CDN. The origin server's identity is intentionally hidden. The checker reports what is publicly visible and labels CDN networks clearly.
Location is derived from the IP's registered network data plus latency measurements from 10 global probe locations, which is accurate to the city or region level in most cases. Anycast networks can make one IP appear in multiple places — the tool accounts for that.
Yes — unlimited lookups with no signup and no account required. Every check runs live against current DNS and network data, and you can re-run it anytime to see whether a site has changed hosts.
