Domain Hosting Checker

What is this hosting checker?

This free website hosting checker tells you exactly what sits behind any domain. Enter a domain and it returns the hosting provider, web server, DNS setup, and registrar in four clear cards. It is the fastest way to check who is hosting a website without digging through command-line tools.

Marketers, developers, and IT admins use a domain hosting checker to research competitors, plan a migration, or diagnose why a site's email or DNS is misbehaving.

How to check who is hosting a website

1. Type or paste the domain (for example example.com) into the box above.
2. Click the button to run the lookup.
3. Read the four result cards: Hosting, Server, DNS, and Registration.

What each result section means

Hosting — the provider or ISP behind the site, its ASN, datacenter, and country (with flag), plus the reverse-DNS name of the resolved IP address. This is how you find the hosting provider for any domain.

Server — the detected web server (nginx, Apache, or LiteSpeed) read from the HTTP response headers, plus a CDN badge such as "Behind Cloudflare" when the site sits behind a content-delivery network.

DNS — the live A and AAAA records, the MX record (which mail host handles email), the nameservers, and TXT/SPF records. Useful when email is bouncing or a record has not propagated.

Registration — the registrar, the created, updated, and expiry dates, the domain status flags, and the authoritative nameservers, pulled via RDAP, the modern successor to WHOIS.

Common use cases

• Competitor research — see which host and CDN a rival site trusts before you choose your own.
• Migration checks — confirm the new provider and nameservers took effect after a move.
• Email and DNS diagnostics — verify MX, SPF, and A records when mail or the site goes down.
• Due diligence — check a registrar and expiry date before buying a domain or a business.

Frequently asked questions

How do I check who is hosting a website?

Enter the domain in the hosting checker above and run it. The Hosting card names the provider, ISP, and datacenter behind the resolved IP address, so you instantly see who hosts the site.

Can this domain hosting checker find the web server too?

Yes. The Server card reads the site's HTTP headers to detect nginx, Apache, or LiteSpeed, and flags a CDN like Cloudflare when one is in front of the origin.

Why can't it find the hosting provider for some domains?

If a site sits fully behind a CDN or proxy, the visible IP belongs to that network, not the origin host. The tool reports what is publicly resolvable, which is the same information any visitor's browser sees.

Is the website hosting checker free?

Yes. It runs in any browser on desktop or mobile with no sign-up, and you can check as many domains as you need.
