Frequently Asked Questions

The Registration Data Access Protocol is the official, structured replacement for WHOIS. Registries publish it as JSON, which the tool reads directly.

Most registrars redact personal contact details for privacy (GDPR). The registrar, dates and status are still public.

It's a normal lock that stops the domain being transferred to another registrar without your approval. It protects against hijacking.

Some country-code registries don't run an RDAP service yet. Use that registry's own WHOIS website instead.
