FAQ

How is the subdomain separated from the root?

The tool splits the host at the registered domain. Everything before the root domain is the subdomain prefix, so api.blog.example.com gives subdomain api.blog and root example.com.

Are nested subdomains returned?

Yes — all labels before the root domain are shown together as one prefix.

Is it free and private?

Yes — free and runs entirely in your browser.
