Who Is Hosting This Website?

Identify the hosting provider and network owner of a domain: IP address, network name and organization from IP whois data.

How the tool identifies a site's host

You enter a domain, the tool resolves it to an IP address, then looks up that address in the regional internet registry's whois data (ARIN, RIPE NCC, APNIC, LACNIC or AFRINIC). The result identifies the organization that owns the network the IP belongs to: the hosting provider or data center where the site physically lives. It also shows the country and the PTR record, the reverse DNS name of the address, which often reveals the provider's name. From a single domain you get a snapshot of the infrastructure: where the server is and who runs it.

Why it helps to know where a site is hosted

The information is useful both for your own projects and for market research.

  • Competitor research: see which kind of infrastructure and which countries sites in your niche run on.
  • Finding your own host: if you lost track of an old hosting account, IP whois tells you who to contact.
  • Checking location: confirm the server is close to your audience, for example in a US data center for US visitors.
  • Due diligence before buying a site: see the real infrastructure before the deal.

Why you sometimes see a CDN instead of the real host

If the site runs behind a content delivery network, the domain points to the nearest CDN edge node rather than the hosting server. In that case whois shows the CDN's network owner, and the actual host cannot be identified from the IP alone because the origin server is hidden behind the proxy. That is normal: the CDN sits in front of the host to speed up delivery and absorb attacks. The PTR record and network owner usually make it clear that you are looking at a CDN rather than the origin server. Once you know the provider, you can look it up in our hosting directory.

Frequently asked questions

How do I find out which host a website uses?
Enter the domain: the tool finds its IP address and uses whois to identify the network owner, country and PTR record. That is usually enough to name the provider or data center.
What is a PTR record?
It is a reverse DNS record that maps an IP address to a hostname. It often contains the name of the hosting company or data center.
Why does the tool show a CDN instead of the real host?
If the site uses a content delivery network, the domain points to a CDN edge node rather than the hosting server, so the origin stays hidden behind it.
Can I get a competitor's exact server address from its IP?
No. IP whois shows the network owner, country and PTR record, not a physical street address. That is enough to evaluate the platform, not more.
Why check a competitor's hosting?
To see which class of infrastructure and which regions sites in your niche rely on, which helps you choose a comparable platform for your own project.
What if I forgot which provider hosts my site?
Run your domain through this tool: IP whois shows the network owner, which tells you which provider to contact to recover access.
