Free Website Hosting Checker — Find Out Who Hosts Any Site

This tool identifies the hosting provider behind any website by tracing its IP address and network ownership back to the company that runs the server. Enter any domain and you'll see which host or cloud provider serves the site, along with the underlying network details.

Knowing where a site is hosted is useful for both research and troubleshooting. If you're choosing a host, seeing which providers your favorite fast sites use is a practical shortlist. If you're vetting a competitor, their host hints at their scale and budget. And if your own site is slow or unreliable, confirming the host and its location helps you decide whether the infrastructure — not your code — is the bottleneck. Server location also affects latency for your real users and can matter for data-residency and privacy requirements.

Use this tool to identify your own host (handy when you've inherited a site or lost the paperwork), to research the hosting choices behind sites you admire, to confirm a migration actually moved you to the new provider, or to gather background before a redesign or transfer. It turns an opaque IP address into a recognizable company name in one step.
