Website hosting checker: who hosts this site?
Find the hosting company behind any website in seconds, plus its CDN, CMS, name servers and email provider. Honest results: when a CDN hides the real host, we tell you instead of guessing.
A real "who hosts this" result: network owner, server hostname, CDN, CMS, name servers and email provider, all on one screen.
What the checker looks at
| Signal | What it reveals | Reliability |
|---|---|---|
| IP owner (ASN) | Which network the server's IP belongs to: HostGator, Amazon, Hetzner, Cloudflare | high |
| Reverse DNS | The server's own hostname, often with the host's name in it | high |
| HTTP headers | Platform fingerprints: Kinsta, WP Engine, Shopify, Vercel, Netlify, WordPress.com | high |
| Name servers | Who runs the DNS; often, but not always, the host | hint only |
| MX records | The email provider, which is often separate from the web host | context |
| Page source | The CMS or site builder: WordPress, Shopify, Wix, Squarespace | high |
Host, registrar, DNS and email: four different things
A domain can be registered at Namecheap, use Cloudflare for DNS, run on a HostGator server and send email through Google Workspace. Most "who hosts this" confusion comes from mixing these up. The checker reports each one separately, and the DNS lookup shows the raw records behind them.
What to do with the answer
- Checking a competitor's fast site? See the host's real prices and renewals before you copy their choice.
- Lost track of your own hosting? The result tells you which company to search your inbox for.
- Taking over a client's site? Note the host, DNS and email providers before touching anything; the switch checklist covers the rest.
FAQ
How do I find out who hosts a website?
Enter the domain in the checker. It looks up the site's IP address, finds which company owns that IP block (its ASN), reads the server's reverse DNS hostname and HTTP headers, and combines the signals into a verdict with a confidence level.
Why does the checker say Cloudflare instead of the real host?
The site uses Cloudflare (or another CDN or firewall) as a proxy, so its real server IP is hidden. We say so instead of guessing, and show the clues that remain, such as name servers and email records.
Is the hosting checker free?
Yes, with no sign-up. It uses only public information: DNS, IP registries and the site's public HTTP response.
Can I find out who hosts a website without a tool?
Partly: run nslookup example.com to get the IP, then look up the IP owner in a WHOIS or ASN registry, and check the reverse DNS of the IP. The checker does all of this in one step and recognises the big hosts' networks and headers.
How accurate is it?
When a site isn't behind a CDN, the IP owner identifies the network reliably. Resellers and small hosts often rent servers from bigger providers, so the result may show the data center company (for example Amazon or Hetzner) rather than the brand you pay. We show the evidence so you can judge.
Who hosts my own website?
Check your domain here, then match the result with your invoices or email. Remember that your domain registrar, DNS provider, web host and email provider can be four different companies.
