Website hosting checker
Find a website's hosting provider
Check DNS, IP ownership, CDN clues, SSL certificates, headers, and email records to separate host, CDN, and domain registrar signals.
Try:
What this checks
- Hosting provider and CDN clues from DNS, IP, and headers
- Nameservers, CNAME, MX, SSL organization, and registrar context
- Full infrastructure context instead of one flattened provider label
How I treat the evidence
Hosting is messy. DNS, CDN, registrar, and email can point to different companies, so the page keeps those signals separate.
The best answer is usually a short evidence trail, not one provider name with no context.
Why does the CDN show instead of the origin host?
If a CDN sits in front, public DNS and headers may only expose the CDN. WhosBuilt shows that split instead of hiding it.
Can this find email hosting too?
Yes, when MX records expose it. Email hosting is shown as a separate clue, not mixed into web hosting.
