Hosting Checker — Find Who Hosts a Domain
Find out who hosts a domain. This checker resolves the domain to its IP and identifies the hosting provider or network behind that address.
Want to know which company keeps a site online? This tool resolves the domain to its IP, then identifies the network that owns that address — which typically corresponds to the hosting provider, data centre, or cloud platform serving the site.
How the host is inferred — and its limits
Hosting providers own the blocks of IP addresses their customers' sites answer from, so looking up who owns a site's IP usually points straight at the host. That makes it useful for competitor research or working out who to send an abuse report to.
Two things blur the answer. When a site sits behind a CDN or proxy, the IP you resolve belongs to that network's edge, so the tool reports the CDN and the real origin stays hidden. And on cloud platforms or resellers, the network owner is the cloud provider, not the retail brand you'd actually buy hosting from — accurate for the infrastructure, one layer off from the storefront.
Frequently asked questions
- Why does it say Cloudflare instead of the real host?
- Because the site is behind Cloudflare's proxy, so the IP resolves to Cloudflare's edge rather than the origin server. The underlying host is deliberately masked in that setup.
- Why might two tools name different hosts?
- IPs change, a domain with several addresses can resolve to different networks, and CDN edges add another layer — enough for two lookups to reasonably report different providers.
