Who is hosting this website? Free hosting checker.
Enter any website to see which company hosts it, how that was found, and the rest of its setup: IP address and network owner, CDN, web server, DNS provider and email provider. When a CDN such as Cloudflare hides the real host, the checker says so instead of guessing, which is where most hosting checkers get it wrong.
Paste any website address. The result takes a few seconds.

Three ways to find a website's host.
The checker combines three public sources and uses the most reliable one it can get. First, the site's response headers: managed hosts such as Kinsta, WP Engine, WordPress.com, Vercel, Netlify, Pantheon and Shopify add their own headers to every page, which names the host directly. Second, the reverse DNS name of the server's IP address: shared hosts usually name their servers after themselves, so an address like premium215-5.web-hosting.com points to Namecheap. Third, the network that owns the IP address, looked up through Team Cymru's public IP-to-ASN service, which names clouds and large hosts such as Amazon Web Services, Google Cloud, DigitalOcean, Hetzner and OVHcloud.
Each result says which of these it came from, so you know how much weight to give it. A header is a direct statement from the host; a network owner tells you whose data centre the server sits in, which for a cloud like AWS or Google Cloud may be the infrastructure behind a smaller host.
| Result | What it tells you |
|---|---|
| Hosting company | Who runs the server, and whether that came from headers, reverse DNS or the network |
| Behind Cloudflare (or Fastly, Akamai) | A CDN sits in front of the site and hides the real host's address |
| Network and ASN | The organisation that owns the IP address range, and the country it's registered in |
| CDN and web server | Content delivery network and server software, such as Nginx or LiteSpeed, from the headers |
| DNS provider | Who runs the domain's nameservers, often the registrar or Cloudflare |
| Email provider | Where the domain's email is handled, such as Google Workspace or Microsoft 365, from its MX records |
Behind a CDN
Why some sites' hosts can't be found.
When a site uses Cloudflare, Fastly or Akamai in front of its server, the public IP address belongs to the CDN, not the host. Many hosting checkers then report Cloudflare as the host, which is wrong: Cloudflare is in front of the site, and the real server could be anywhere. This checker reports the CDN and says the host is hidden, unless the site's headers still name a managed host, as Kinsta and WP Engine sites usually do. Short of the site owner telling you, there's no reliable public way to see past a CDN.
Why it's useful
What people use a hosting checker for.
Agencies and developers check hosting before quoting for work, because a site on a managed WordPress host, a cheap shared plan or a cloud server needs different access and handles traffic differently. Site owners check where a competitor or a site they admire is hosted. Buyers of a website or business check what they're taking over. And when a site is slow or down, knowing the host, the CDN and the DNS provider tells you who to contact.
Paired with the website platform checker, which shows the CMS, page builder and framework, you get most of a site's technical setup from two quick checks.
Limits
What the checker can't see.
The network country is where the IP range is registered, not necessarily where the server is. Reverse DNS names are set by the network owner and some hosts don't set them, and resellers run on bigger hosts' servers, so the checker may name the underlying company. Large sites often use several providers at once, for different regions or for email and DNS. Each check makes a few public DNS lookups and one request to the home page for its headers; nothing is stored, and checks are rate-limited.

Questions
Hosting Checker FAQs
How do I find out who is hosting a website?+
Enter the address above. The checker reads the site's headers, the reverse DNS name of its server and the network that owns its IP address, and names the host along with how it was found. If a CDN such as Cloudflare hides the host, it tells you that.
Why does it say the host is hidden behind Cloudflare?+
The site's public IP address belongs to Cloudflare, which sits in front of the real server. Cloudflare doesn't reveal the server behind it, so no outside tool can reliably name the host unless the site's own headers do.
Can I find a website's IP address and server location?+
The checker shows the IP address, the network that owns it and the country the network is registered in. The registration country is a good hint but not always where the server physically sits, especially for clouds and CDNs.
How do I find a website's DNS and email provider?+
They're in the results: the DNS provider comes from the domain's nameservers, and the email provider from its MX records, such as Google Workspace or Microsoft 365.
Is the hosting checker free?+
Yes, with no sign-up. Each visitor can run up to 20 checks every 10 minutes.
