What "who hosts this website" really means
A website can involve several companies at once. Here is what each part of the answer tells you.
A domain points to IP addresses
DNS turns a name like example.com into IPv4 and IPv6 addresses. Browsers connect to those addresses, so the company running them is the one serving the site to visitors.
Every IP belongs to a network
IP addresses are allocated in blocks to networks with an Autonomous System Number (ASN), such as AS16509 for Amazon or AS13335 for Cloudflare. The network owner is the most reliable single clue to where a site runs.
CDNs and platforms sit in front of servers
Many sites put a CDN or a managed platform in front of their server. Then the IP belongs to the CDN, and clues like a CNAME to cname.vercel-dns.com or wpengine.com reveal the platform. The origin server behind a CDN stays hidden.
DNS, website and email can use different companies
The nameservers (who answers DNS), the web host and the email provider are often three separate services. This report shows each one separately, for example Cloudflare DNS, a site on AWS and email on Google Workspace.
Common hosting setups and how to spot them
The signals in your report that point to each kind of hosting.
| Setup | Examples | Signals in this report | What it means |
|---|---|---|---|
| CDN or proxy | Cloudflare, Fastly, Akamai, Amazon CloudFront | The network owner is the CDN, Cloudflare nameservers, or a CNAME to cloudfront.net, fastly.net or edgekey.net. | Visitors reach the CDN, which forwards requests to a hidden origin server. The real host cannot be seen from public DNS. |
| Cloud platform | Amazon Web Services, Google Cloud, Microsoft Azure | Network AS16509 (Amazon), AS15169 or AS396982 (Google) or AS8075 (Microsoft), and reverse DNS such as compute.amazonaws.com. | The site runs on rented cloud servers, either directly or through a hosting company that resells cloud capacity. |
| Managed platform | Vercel, Netlify, WP Engine, GitHub Pages, Heroku | A CNAME to cname.vercel-dns.com, netlify.app, wpengine.com, github.io or herokudns.com. | A platform that deploys and runs the site for the owner. It usually runs on a cloud or CDN underneath. |
| E-commerce or website builder | Shopify, Wix, Squarespace, WordPress.com, Blogger | A CNAME to shops.myshopify.com, wixdns.net, ext-cust.squarespace.com or ghs.google.com. | An all-in-one service that hosts the site, the design tools and often the domain DNS. |
| VPS or dedicated server | DigitalOcean, Hetzner, OVHcloud, Linode, Vultr | The network owner is the provider, and reverse DNS often names it (for example your-server.de for Hetzner). | The owner rents a whole virtual or physical server and manages it, or a smaller host resells it. |
| Shared hosting | Hostinger, GoDaddy, Bluehost, HostGator | The network owner is the hosting company, and nameservers such as dns-parking.com or domaincontrol.com. | Many websites share one server and often one IP address, managed by the hosting company. |
How this tool works
What happens between entering a domain and seeing the report.
Your input is cleaned up
We remove https://, paths, ports and login details, keep the exact hostname you typed (www included) and convert international domain names to their ASCII form.
Our server queries public DNS
It reads the A and AAAA records (IP addresses), the CNAME chain, the nameservers and the mail servers. Private or internal addresses are refused.
The main IP is looked up
The first IPv4 address (or IPv6 if there is none) is sent to ip-api.com for network owner, ASN and approximate location. Your own IP address is not sent.
Known patterns are matched
CNAME targets, reverse DNS, network owner, nameservers and mail servers are compared with known hosts, CDNs, platforms and email providers. Every match is listed as evidence.
The result is cached briefly
Each domain's result is kept for 30 minutes so repeat checks are fast, then it expires. The website itself is never contacted.
What this tool does, and what it doesn't
A plain list, so you know exactly what to expect.
This tool does
- Show every IPv4 and IPv6 address the domain uses
- Identify the network owner and ASN
- Name the likely hosting platform, with evidence
- Show the DNS and email providers
- Show reverse DNS and approximate server location
- Copy or download the full report
This tool does not
- Reveal an origin server hidden behind a CDN
- Name resellers that rent another company's servers
- Show who owns the domain (use a Whois lookup)
- Visit or scan the website you check
- Keep a history of the domains you check
- Require an account
Where your data goes
Our server looks up the domain in public DNS, then sends only the resolved IP address of that website (not your IP address) to ip-api.com for network and location data. The website you check is never contacted, and each result is cached for 30 minutes. Like any website, our server may keep normal access logs, as described in our privacy policy.

Why your results might look unexpected
The six surprises people ask about most, and what each one means.
It shows Cloudflare, not the real host
The site uses Cloudflare as a proxy, so its DNS points to Cloudflare. Visitors connect to Cloudflare and the origin server stays hidden. That is the correct public answer.
It shows AWS, Google Cloud or Azure
Many hosts and platforms run on the big clouds. Look at the evidence: a CNAME or reverse DNS name often reveals the platform on top, such as Vercel or WP Engine.
It shows a data centre, not my hosting company
Smaller hosts and resellers often rent servers from larger companies. The IP is registered to the company that owns the network, not to the brand that sells the hosting.
Could not resolve the domain
The name has no A or AAAA records. Check the spelling, try with or without www, and note that new, parked or email-only domains may have no website records yet.
www and the bare domain differ
They are separate DNS records. One may point to the hosting server and the other to a CDN or platform. This tool checks exactly the name you enter.
The IP changes between checks
Large sites return different IPs for load balancing and to send visitors to a nearby server. The network owner usually stays the same even when the IP changes.
Questions about hosting checks
How does this tool find who is hosting a website?
It looks up the domain in public DNS to get its IP addresses, CNAME chain, nameservers and mail servers, then finds the network that owns the main IP address using ip-api.com. Finally it matches all of that against known patterns for hosts, CDNs, cloud platforms and website builders, and shows the evidence for its answer.
Why does it show Cloudflare instead of my real host?
Because visitors really do connect to Cloudflare. When a site uses Cloudflare as a proxy, its DNS points to Cloudflare's servers, which forward requests to the hidden origin server. Public DNS cannot see past the proxy, so the result correctly shows the network your visitors reach.
Can I find the real server IP behind a CDN?
Not with this tool. CDNs hide the origin server on purpose, and this tool only reads public DNS. Sometimes the origin shows up in old DNS records, mail server records or certificate logs, but that is outside what a hosting check should do, and well-configured sites block it.
Is the location shown where the server really is?
It is an estimate based on the IP address. For CDNs and anycast networks the same IP is served from many cities, so the location is often the provider's registered address rather than one server. Country is usually more reliable than city.
Why do www and the bare domain show different results?
They are separate DNS records and can point to different places. A common setup sends example.com to the hosting server while www.example.com is a CNAME to a CDN or platform. This tool checks exactly the name you enter, so try both.
Why does it not show who owns the website?
Hosting and ownership are different things. This tool shows the infrastructure that serves the site. Domain ownership comes from registration records, which you can check with a Whois lookup, although most owners now hide their details for privacy.
Are the domains I check stored?
The result for each domain is cached on our server for 30 minutes so repeat checks are fast, then it expires. The domain is not linked to you or kept in a history. A hashed, temporary copy of your IP address is used only for rate limiting and expires within 24 hours. Like any website, our server may keep normal access logs, as described in our privacy policy.
