How the most popular websites are hosted
We check about 1,000 of the most visited websites every week. Of these, 73% sit behind a content delivery network and 43% support IPv6. Cloudflare serves the most of them. See the full report →
Well-known IP addresses
How it works
1. Find the addresses
We look up the website's IP addresses in public DNS.
2. Identify the network
IPinfo data tells us which company owns each address, and where it is.
3. Spot CDNs and providers
We detect CDNs that hide the real host, plus the DNS and email providers.
Questions about finding a website's host
How can I find out who hosts a website?
Enter the website's address above. We look up its IP addresses in public DNS, then find out which network owns each address and where it is. You can do the same by hand: run "dig example.com" or "nslookup example.com" to get the IP address, then look that address up in a WHOIS or IP database to see the organisation it belongs to.
Can you find the real host of a website behind Cloudflare or another CDN?
No, and nobody should publish it. A content delivery network such as Cloudflare, Akamai or Fastly sits in front of the website and deliberately hides the servers behind it, partly to protect them from attacks. A lookup shows the CDN, and we say so rather than guessing. Sometimes public DNS reveals a hosting platform such as Shopify or WP Engine, and then we name it.
Why is the hosting company different from the domain registrar?
They do different jobs. The registrar sells and renews the domain name, and a WHOIS lookup for the domain shows it. The hosting provider runs the servers that deliver the website. Many websites buy their domain from one company and host with another, so a domain WHOIS rarely tells you who the host is.
What is an ASN?
An autonomous system number identifies a network on the internet, such as AS15169 for Google or AS13335 for Cloudflare. Every IP address is announced by one of these networks, so the ASN tells you which organisation is responsible for the address a website uses. Large companies often run several ASNs.
Why can the server country change between lookups?
Big websites and CDNs run servers in many countries and send each visitor to a nearby one. Depending on where the lookup comes from, the same website can answer from a different country. Our checks run from Europe, so the country we show is the server we reached from there.
What's the difference between a hosting, DNS and email provider?
The hosting provider serves the website, the DNS provider answers lookups for the domain name, and the email provider receives the domain's mail. A website can use three different companies for these, for example Amazon Web Services for hosting, Cloudflare for DNS and Google Workspace for email, so we show each one separately.
Is it free, and do you keep what I look up?
It's free, with no sign-up. We log each lookup for a month to keep the service running and to see which websites are popular, and we don't use cookies or analytics.
