FREE WEBSITE INFRASTRUCTURE LOOKUP

Who hosts this website?

Enter a domain to inspect its public DNS signals and see what they can—and can’t—tell you about its hosting.

Enter a domain only. Do not include a page path, username, or password.

This tool sends DNS questions to Cloudflare’s public DNS resolver and registration lookup requests to the relevant public RDAP registry. Results are not stored by Hosting Review Lab.
HOW THIS WORKS

Clues, with their limits made clear.

The lookup reads public A, AAAA, CNAME, and NS DNS records, then checks public RDAP registration data where available. Nameserver brands can reveal a DNS service. IP registration can reveal a network operator. Neither alone proves which hosting plan or provider serves the website.

Data sources: Cloudflare DNS over HTTPS and the IANA RDAP bootstrap registry.
