Want to know which company hosts a website? The Hosting Checker looks up the server behind a domain, finds the network that owns that server, and tells you the hosting company, server IP, location and name servers. It also tells you when a site hides behind a CDN like Cloudflare, so you are not misled by the wrong answer.
How the hosting checker works
Every website lives on a server with an IP address. Blocks of IP addresses belong to networks, and each network is registered to a company, such as a hosting provider or a cloud platform. The checker follows that chain:
-
DNS lookup. It finds the domain’s A record, which is the IP address visitors connect to.
-
Network lookup. It looks up which organisation owns that IP and its network number (ASN), plus the approximate location of the server.
-
Fingerprint match. It compares the network name and the domain’s name servers with a list of well known hosts and services to name the company in plain words.
-
CDN check. If the IP belongs to a CDN or proxy like Cloudflare, Fastly or Akamai, the tool says so clearly.
How to use it
-
Type the domain, like example.com. You can paste a full URL.
-
Press Find host.
-
Read the main answer. The hosting company or network name appears in large type with a short note on how sure the tool is.
-
Check the details. Server IP, network and ASN, server location, who manages the DNS, and the name servers.
Reading the results
| Field | What it tells you |
|---|---|
| Host | The hosting company or cloud platform that owns the server network. |
| Server IP | The address visitors connect to. |
| Network | The organisation that owns the IP block, with its ASN (network number). |
| Server location | The approximate city and country of the server or the network’s registered location. |
| DNS managed by | The company whose name servers answer for the domain. This can be different from the host. |
| Name servers | The exact name servers listed for the domain. |
When the real host is hidden
Many sites use a CDN or a security proxy in front of their server. Cloudflare is the most common. When that happens, the domain points to the proxy’s IP, not to the real server. The checker will show Cloudflare (or another CDN) as the host, and say that the real hosting company is hidden.
That is by design. Hiding the origin server protects it from attacks and is a normal, recommended setup. There is no reliable public way to find the server behind a well configured proxy, and trying to bypass it is not something this tool does.
Name servers can still give a hint. A site using Cloudflare for DNS shows Cloudflare name servers, but a site using a host’s own name servers with Cloudflare only as a proxy may show the host’s name servers. The “DNS managed by” line helps you spot that difference.
Why the host and the DNS provider can be different
It is very common for a domain to be registered at one company, have DNS at a second, and be hosted at a third. For example:
- Domain registered at Dynadot.
- DNS managed by Cloudflare.
- Website hosted on Hostinger.
The registrar appears in the WHOIS Lookup, the DNS provider in the name servers, and the host in the network of the A record. This tool shows the last two together.
Good reasons to check a site’s hosting
Choosing a host for your own site
If a site you admire is fast and reliable, it is useful to know where it is hosted. Check a few sites in your niche and you will often see the same hosts again and again.
Taking over a website
When you inherit a site from a previous developer or buy an existing website, the first question is where it lives. This tool tells you which company to contact or log in to.
Troubleshooting after a move
If you moved your site to a new host but still see the old version, check the host here. If it still shows the old company, the DNS has not been updated or has not spread yet.
Reporting abuse
If a site is sending spam or hosting a scam, knowing the host lets you report it to the right company’s abuse team.
Checking for shared hosting neighbours
Many small sites share one IP on shared hosting. That is normal and not a problem for most websites.
Shared, cloud, VPS: what the network tells you
The network name often hints at the type of hosting:
- Hosting brands like Hostinger, Bluehost, SiteGround or GoDaddy usually mean shared or managed hosting.
- Cloud platforms like Amazon Web Services, Google Cloud or Microsoft Azure mean the site runs on cloud servers, often managed by an agency or a platform built on top.
- VPS providers like DigitalOcean, Hetzner, Vultr, Linode or Contabo usually mean someone set up their own server.
- Platforms like Vercel, Netlify, Shopify, Wix or WordPress.com mean the site is built on that service rather than on traditional hosting.
Hosting signs you can read without any tool
Sometimes the page itself gives hints that confirm what the checker found:
- WordPress sites often load files from paths starting with /wp-content/, which tells you the platform, though not the host.
- Shopify, Wix and Squarespace stores load images from their own content domains.
- A “Powered by” line in the footer sometimes names the host or builder.
- Default parking pages from registrars mean the domain has no real hosting yet.
Combine these hints with the network result above and you will usually have a clear picture.
How accurate is it?
For sites not behind a CDN, the network owner is accurate, because it comes from the official records of who owns the IP address. The friendly host name depends on matching that network with known companies. Smaller or regional hosts may show their network name instead of a brand name, and some hosts rent servers from bigger networks, so a site on a small host may show the data centre company. The server location is approximate and based on IP data.
Moving your site to a new host without downtime
If you are checking hosting because you plan to move, this order keeps your site online the whole time:
-
Back up everything at the old host: files, database and email if you use it there.
-
Set up the site at the new host first. Many hosts, including Hostinger, offer free migration and do this for you.
-
Test the new copy using the temporary address the new host gives you, before touching DNS.
-
Lower the DNS TTL a day before the switch so the change spreads faster.
-
Update DNS to point the domain at the new host, by changing name servers or the A record.
-
Confirm the move here. Run this checker again. When the host shows the new company, the switch is live for most visitors.
-
Keep the old hosting for a week before cancelling, in case some visitors still reach the old server.
After the move, confirm the certificate with the SSL Checker and the response with the Website Status Checker.
What an ASN is and why it helps
An ASN (autonomous system number) is the ID of a network on the internet. Every hosting company, cloud provider and internet provider that runs its own network has one. Two sites with the same ASN are on the same company’s network, even if their IPs look different. When the tool shows something like AS15169 (Google) next to the network name, that number points to the exact network that carries the site’s traffic. You can look up any IP’s network with the IP Address Lookup.
Picking a host for your own website
If you are starting out, here is what matters more than any brand name: a data centre close to your audience, free SSL, daily or at least weekly backups, a simple dashboard, and support that answers. For a first blog, portfolio or small store, Hostinger checks those boxes at a low price. My Hostinger guide covers plans and setup step by step.

Frequently asked questions
Can this tool find the real host behind Cloudflare?
No. When a site uses Cloudflare as a proxy, the real server is hidden on purpose. The tool shows Cloudflare and tells you the real host is not visible.
Is the hosting checker free?
Yes. It is free for normal use with no signup.
Why is the DNS provider different from the host?
Domains often use DNS from one company and hosting from another. Both are normal setups, and the tool shows them separately.
Is the server location exact?
No. IP locations are approximate and may show the network’s registered location rather than the exact data centre.
Why does it show a data centre company instead of a hosting brand?
Some hosting companies rent servers from larger networks. The IP then belongs to the data centre, so that name appears.
Can I see every site hosted on the same server?
No. This tool shows the host of one domain. It does not list other sites on the same IP.
Does the tool show the registrar of the domain?
No. The registrar is a different company from the host. Use the WHOIS Lookup to see where the domain is registered.
