Website Hosting Checker
Resolves the site to its IP, asks the regional internet registry who owns that network, and detects when a CDN is hiding the real server.
How host detection works
The checker resolves the domain to its IP addresses, queries the regional internet registry (via RDAP) for the network that owns them, performs a reverse-DNS lookup on the IP, reads the response headers for CDN fingerprints, and lists the domain’s name servers. Together these four signals identify the operator in the overwhelming majority of cases, and, just as importantly, tell you honestly when a CDN makes the origin unknowable from the outside.
Why “who hosts this” is a daily question for us
Clients come to us with sites they own but cannot access: the developer disappeared, the agency dissolved, the invoices stopped arriving. Step one is always identifying where the site physically lives, because that is who can hand over a backup. This tool is the exact first step of our own recovery workflow, made public. If the trail ends at a CDN and nobody has credentials, the fallback is rebuilding from the public pages, which is precisely what our cloning service does.
Reading the report like we do
Network owner plus reverse DNS agreeing on one company: that is your host, contact them. Cloudflare in the CDN line with generic name servers: origin hidden, look for the owner through billing records instead. A big cloud (AWS, Google Cloud, Hetzner) as owner: the site is self-managed by whoever holds the cloud account, and there is no support desk to email. Each pattern changes who you call next, and the report is built to make that obvious.
Frequently asked questions
Why does the report say Cloudflare instead of the real host?
Because that is genuinely who answers the requests. Sites behind Cloudflare, CloudFront or another CDN publish the CDN's IPs, and the origin server is deliberately hidden. The report says so explicitly rather than guessing; the name servers and reverse DNS sometimes still hint at the origin provider.
I need to leave my current host but I do not know who it is. Can this help?
Usually, yes: for the majority of small-business sites the network owner in the report is the hosting company, and with the host identified you (or we) can request access or a backup. If the site hides behind a CDN and the previous developer is unreachable, we rebuild sites from their public pages daily; that is our cloning service.
What is reverse DNS and why does it matter here?
Reverse DNS is the name the IP itself reports back, and hosts often encode themselves into it (server123.hetzner.com tells you everything). It is a second, independent hint that frequently identifies the provider even when the network registration is generic.
Does who hosts a site affect its SEO?
Only through performance and reliability: a slow or frequently-down host hurts, the brand name on the invoice does not. Do not move hosts chasing rankings; move for speed, support and backups. When you do move, our migration service carries the SEO safely.
