A worked example
Input
https://sales.example.co.uk/contact jane@example.co.uk
Output
example.co.uk — 2 occurrences
The Public Suffix List identifies co.uk as a suffix, so the registered domain is example.co.uk rather than co.uk.
What the result means
Registered-domain mode groups subdomains under the same site while respecting known private suffixes. Full-hostname mode keeps entries such as sales.example.com separate.
A domain is not proof of an active website or a company. Known private suffixes are respected; unknown suffixes and IP addresses are excluded.
Frequently asked questions
What is the difference between a hostname and a registered domain?
A hostname can include a subdomain, such as sales.example.com. Registered-domain mode returns example.com. Known private suffixes such as github.io are respected, so independent hosted sites stay separate.
Does a domain result confirm an active business?
No. No website or company lookup is performed. The result comes from supplied text; verify the company’s activity, ownership and fit separately.
