Who is hosting a website?

How it works

The tool resolves the domain to its IP address, then looks up which network owns that address. The provider shown is the company the IP block is registered to — usually the hosting company or cloud platform.

Sites behind a CDN

If a site uses a content delivery network such as Cloudflare, Fastly, Akamai or Amazon CloudFront, the result shows the CDN, not the server behind it. That is by design: the CDN sits in front and hides the real (origin) server. The mail servers (MX lookup) or other subdomains sometimes point elsewhere, but there is no reliable way to see the origin.

Common uses

• Reporting a phishing or malware site to the company that hosts it — hosts act fastest on reports sent to their abuse contact.
• Checking that a website migration finished after a DNS change.
• Confirming where data is hosted, for example inside the EU.
• Seeing which platform a competitor or supplier uses.
