Fetch WHOIS registration data for domains.

The tool gives a fast ownership overview without manual CLI parsing. Use it as an initial intelligence step before escalation.
Enter values in the left panel, keep units explicit, run the calculation, then copy or share the result. Invalid fields are highlighted immediately.
