Observed network provider

The provider belongs to the observed public IP. If a CDN or reverse proxy is present, it may hide the origin hosting provider. Country is an IP-dataset estimate, not the physical location of the website owner.

Hosting Checker

Enter a URL

A hosting checker shows which network a website runs on. Enter any domain in this free hosting checker and you get its IP address, the provider or ISP that owns that address, the country, the reverse DNS name and the nameservers. It is built for site owners, marketers and developers who want a quick answer to "who hosts this site?"

What Is Web Hosting and How Can You Tell Who Provides It?

Web hosting is the service that stores a website's files on a server connected to the internet, so visitors can load the site at any time. When you ask what is hosting a website, you are really asking which company owns the server and the network it sits on.

A domain name does not contain that answer. You find it by following the domain to its IP address, then looking at who operates that address. The tool does exactly this and puts the findings on one results page:

IP address: the numeric address the domain currently points to.
Network or service provider: the ISP or hosting company that operates that IP address.
Country: where that IP address is registered or located.
Reverse DNS: the hostname the IP address announces for itself, which often contains the host's brand name.
Nameservers: the servers that answer DNS questions for the domain, shown when they can be found.

Together these clues usually point to the host. No single field is a guarantee, so the sections below explain how to combine them.

How to Use the Hosting Checker

You can check the hosting of a website in under a minute with these steps:

Open the tool and find the single text field that shows the example example.com.
Type or paste the domain you want to research. A full address such as https://www.example.com/blog also works, because the tool reads the host name from it.
Click the button under the field. It changes to "Checking..." while the lookup runs.
Read the results page: domain, IP address, network provider, country, reverse DNS and, if available, a Nameservers list.
Compare the provider, reverse DNS and nameservers to decide who hosts the site.
Use the link on the results page to start a new check for another domain.

If the input is not a valid domain, you see an error message and a link to try again. Check for typos, spaces or missing dots first.

Worked Example: Reading a Real-Style Result

Say you run into a competitor's blog, acmeshoes.com, and want to know where it lives. Here is a sample of what a result can look like (the values are illustrative):

IP address: 203.0.113.25
Network or service provider: Example Hosting LLC
Country: United States
Reverse DNS: server25.examplehost.net
Nameservers: ns1.examplehost.net and ns2.examplehost.net

Every clue agrees. The IP belongs to Example Hosting LLC, the reverse DNS uses the same brand name, and the nameservers share that brand too. You can conclude with good confidence that the site is hosted by that company, on a server in the United States.

Now imagine the provider reads "Cloudflare" and the nameservers are Cloudflare names. That tells you the site sits behind a CDN and proxy, not where the original server lives. The real host is hidden by design, and you would need other clues to find it.

How to Read and Act on Each Result

Each field answers a different question, and the best conclusions come from checking whether they agree. This table sums up what to look for.

Field	What it tells you	What to do with it
IP address	Where the domain points now	Look up other sites on the same IP
Network provider	Who operates that IP	Treat as the likely host
Country	Server location of the IP	Judge distance to your audience
Reverse DNS	Hostname tied to the IP	Confirm the host brand
Nameservers	Who manages DNS	Spot DNS or CDN services

When the provider is a known hosting company

If the network provider is a recognizable host and the reverse DNS matches, you have your answer. Note it down for competitor research, or compare it with the host you use now.

When the provider is a CDN or proxy

A CDN name means traffic passes through a front layer before reaching the real server. The result is accurate for what the public sees, but it does not expose the origin host. Try the nameservers and reverse DNS, or look at the site's other subdomains with a separate DNS lookup tool.

When the provider is a big cloud network

Large cloud platforms host everything from small blogs to huge apps. The name tells you the infrastructure but not the company that resells or manages the plan. The nameservers or reverse DNS may reveal more.

When fields show Unavailable or Not Available

Some IP addresses have no reverse DNS name, and some lookups return no location or provider data. That is normal. Run the check again after a short wait, and rely on the fields that did return data.

Country and site speed

As a loose guideline, hosting closer to your main audience reduces the distance data has to travel, which helps load time. If your readers are mostly in Texas and the server is on another continent, consider a closer data center or a CDN. Google's Search Central documentation treats page speed as one part of page experience, not a magic ranking lever, so treat location as one factor among many.

Who Uses a Hosting Checker and When?

This tool is the right pick whenever you need to identify a web host from the outside, with only a domain name in hand.

Competitor research: see whether a rival runs on shared hosting, a cloud platform or behind a CDN, and in which country.
Site migrations: confirm that your domain now points to the new host's network after a move, not the old one.
Outreach and support: find the host of a site that copies your content, so you know where to send an abuse or takedown request.
Troubleshooting: when a site is down or slow, find out which provider runs its server before you contact anyone.
Agency audits: record the host, country and nameservers of every client site in one pass, which makes later handovers easier.
Buying a site: check where a site you plan to buy is hosted, and compare it with the seller's claims.

If you want to see only the numeric address, the domain to IP converter is a lighter option. For a broader review of a domain, browse the full domain tools collection.

Best Practices, Common Mistakes and Troubleshooting

A few habits make the results more reliable and save you from wrong conclusions.

Check the right domain version

Enter the domain the site actually uses. A site can serve its main pages from one host and its blog or shop from a subdomain on another. Run the check on shop.example.com separately if you suspect that.

Compare at least two clues

Never rely on one field. A provider name plus a matching reverse DNS plus matching nameservers is strong evidence. A provider name alone can mislead if a CDN is in front.

Do not confuse domain registrar with host

The company where a domain was bought is often different from the company that hosts the site. Nameservers can hint at either one, so check them against the provider. To see when a domain was registered or when it expires, use the domain age checker or the bulk domain expiry checker.

This tool cannot show your hosting plan or renewal date

Searchers often ask how to check hosting plan details or a hosting expiry date. That information lives in your own account with your host, in the billing or subscription area, and not on the public internet. This tool only identifies who runs a site from the outside.

Recheck after DNS changes

If you recently moved a site, DNS changes can take some time to spread. Results may still show the old provider for a while. Wait a few hours and run the check again.

Investigate shared IPs and reputation

Many small sites can share one IP address on shared hosting. If your email lands in spam or a site seems flagged, run the IP through a blacklist checker to see whether the shared address has a poor reputation.

Limitations to Keep in Mind

The hosting checker reports what is publicly visible for the domain's current IP address, so it shows the most likely host, not a legal confirmation. CDNs, reverse proxies and security services can stand in front of the real server and replace the provider you would expect to see.

Location data refers to the IP address, which may not match the physical address of the company or its staff. A site can also use several servers, for example one for the website and another for email, and this tool reports the one the domain's main address resolves to. Treat the result as a strong lead and confirm it with other signs when the decision matters.

Frequently Asked Questions

How do I check the hosting provider of a website?

Type the domain into the field, run the check, and read the network provider on the results page. Confirm it by comparing the reverse DNS and nameservers. When all three show the same company, that is very likely the host.

What information does the hosting checker show?

The hosting checker shows the domain, its IP address, the network or service provider, the country, the reverse DNS name and, when available, the nameservers. Together these clues point to who hosts the site and where the server sits.

Can I enter a full URL instead of just a domain?

Yes. You can paste a full address such as https://www.example.com/page and the tool reads the domain from it. A plain domain like example.com works too. If the input is invalid, you see an error and a link to try again.

Why does the result show Cloudflare or another CDN instead of the real host?

The site is using a CDN or proxy that sits in front of its real server. The result is correct for the public IP, but it hides the origin host. Check the nameservers and reverse DNS for other clues.

Can this tool check my Hostinger plan or hosting expiry date?

No. Plan details, renewal dates and login information are only available in your own account with your hosting company. This tool identifies who hosts a site from the outside, using the domain's public IP and DNS data.

Is the hosting checker free and does it need a sign-up?

Yes, it is free and needs no sign-in. Enter a domain and run the check as often as you need. For research on competitors, migrations or a slow site, you get results in a few seconds.
