Website Hosting Checker
Enter any website to see which company hosts it. The checker resolves the site's IP addresses, looks up who owns each network and its ASN, recognizes CDNs and website platforms from CNAME records, and shows the approximate server location plus the DNS and email providers.
Last updated:
Enter a website such as example.com and click Check hosting to see which company hosts it, its IP addresses, network, ASN and server location.
How to use the Website Hosting Checker
- Enter a website: a domain such as example.com, a full URL or a subdomain like shop.example.com.
- Click Check hosting. The tool resolves the address with DNS over HTTPS.
- Read the result: the provider name at the top, whether it is a CDN, cloud, web host or platform, and the ASN.
- Check each IP address for its network owner, IP range, reverse DNS, registry and approximate location.
- Look at DNS and email to see who runs the site's name servers and mailboxes, then copy or download the summary.
How the hosting provider is identified
No single record says "this site is hosted by X", so the checker combines several clues, from the most specific to the most general:
| Clue | Where it comes from | Example |
|---|---|---|
| CNAME record | DNS: the name the site is an alias of | shop.example.com → shops.myshopify.com means Shopify |
| Reverse DNS (PTR) | DNS: the hostname set for the IP address | ec2-3-90-1-2.compute-1.amazonaws.com means Amazon Web Services |
| ASN and AS name | Internet routing data, via the Team Cymru IP-to-ASN service | AS13335 CLOUDFLARENET means Cloudflare |
| Network owner | RDAP record from ARIN, RIPE NCC, APNIC, LACNIC or AFRINIC | Network DO-13, owner DigitalOcean, LLC |
| Approximate location | IP geolocation database | Frankfurt am Main, Germany |
Common hosting setups and what they look like
| Setup | What the checker shows | What it means |
|---|---|---|
| Shared or VPS hosting | A web host such as GoDaddy, Hostinger, OVHcloud or Hetzner | The site's server sits directly on that company's network |
| Cloud hosting | Amazon Web Services, Google Cloud, Microsoft Azure, DigitalOcean | The owner rents servers or services from a cloud provider |
| Website platform | Shopify, Wix, Squarespace, Vercel, Netlify, GitHub Pages | The platform runs the site; the owner does not manage a server |
| Behind a CDN or firewall | Cloudflare, Fastly, Akamai, CloudFront, Sucuri, Imperva | The real origin server is hidden; only the CDN is visible |
| Self-hosted | The organization's own name and ASN, such as Wikimedia | Large organizations often run their own network and data centers |
Tips
- Check www and the bare domain separately; they can point to different services.
- Several providers are normal. Big sites spread traffic across networks, so IPs may belong to more than one company.
- To report abuse, contact the abuse address of the network that owns the IP (shown on each IP card), or the CDN if the site is behind one.
- Moving a site? After changing DNS, results can take from minutes to a day to update while old records expire from caches.
Frequently asked questions
How does a hosting checker find the web host?
It looks up the domain's A and AAAA records to get the server IP addresses, then asks who owns those addresses. The owner comes from the regional internet registry (RDAP) and from the autonomous system (ASN) that announces the IP range on the internet. CNAME records and reverse DNS names often reveal the platform too, for example a CNAME to cname.vercel-dns.com means Vercel.
Why does it say Cloudflare when the site is hosted somewhere else?
Cloudflare, Fastly, Akamai, Amazon CloudFront and similar services are CDNs or reverse proxies. The domain points to their servers, which cache the site and forward requests to the real origin server. The origin's address is deliberately hidden, so DNS lookups can only show the CDN. The site owner may host the origin on any provider.
What is an ASN?
An Autonomous System Number identifies a network that controls its own routing on the internet, such as AS13335 for Cloudflare or AS16509 for Amazon. Every public IP address is announced by at least one ASN, so the ASN and its name are a reliable way to tell which company's network a server sits on.
How accurate is the server location?
The country of the IP registration is reliable, but city-level location comes from geolocation databases and is approximate. CDNs use anycast, which means the same IP address is served from many data centers around the world, so the shown location may simply be the company's registered address.
Can I find the hosting company for a site on a shared host?
Yes, in most cases. Shared hosting companies such as GoDaddy, Bluehost, SiteGround or Hostinger own their IP ranges, so the network owner or reverse DNS name points to them. If the site uses a reseller, you will usually see the underlying data center or hosting company instead.
Why do www and the bare domain show different hosts?
The www subdomain and the root domain can have different DNS records. Many sites point www to a platform with a CNAME and use a redirect service or another provider for the bare domain. Check both to get the full picture.
Are my lookups private?
Lookups run in your browser. DNS queries go to Cloudflare or Google DNS over HTTPS, the network owner lookup goes to rdap.org and the Team Cymru IP-to-ASN DNS service, and the approximate location comes from ipwho.is. FreeToolCabin does not receive or store the sites you check.
Are all the tools on FreeToolCabin tested for quality and accuracy?
Yes! Every tool on our site undergoes automated Q/A testing in real browser environments to ensure high precision, correct output, and zero errors. If you happen to spot a bug or have a suggestion, please contact us at [email protected] and our team will review it right away.
