Who Is Hosting This Website?
Estimate who hosts a website by checking DNS, IP address ownership, reverse DNS, RDAP, ASN, nameservers, and HTTP header signals.
Who Is Hosting This Website? estimates the hosting provider behind a domain, URL, or public IP address. The tool resolves the website to public IPv4 and IPv6 addresses, checks nameservers, reverse DNS, RDAP network records, ASN ownership, and HTTP headers, then formats the evidence into a readable hosting report.

What the Hosting Lookup Checks
A website can be hosted directly on a web server, behind a CDN, or through a cloud platform. This tool reviews several public signals instead of relying on a single field: DNS A and AAAA records, CNAME chains, nameservers, reverse DNS, public RDAP allocation records, Team Cymru ASN data, and selected HTTP response headers such as Server, Via, cache, and CDN identifiers.
The likely hosting provider is usually the network owner, cloud platform, CDN, or upstream provider associated with the website IP address. When a CDN or reverse proxy is detected, the result may identify the CDN rather than the private origin server, because the origin is intentionally hidden from public DNS.
How to Use the Web Host Lookup
Enter a domain name, full URL, IPv4 address, or IPv6 address. The report shows the likely hosting provider, primary IP address, resolved addresses, nameservers, reverse DNS, ASN, RDAP network range, country, and HTTP infrastructure signals.
Use the confidence notes when interpreting the result. For example, Cloudflare, Akamai, Fastly, CloudFront, and similar services often protect or accelerate a website while masking the origin hosting provider. In those cases, the visible host is still useful for operational and security review, but it may not be the company running the origin server.
