Technical details
RDAP and WHOIS
RDAP is the structured, modern successor to WHOIS. The tool tries RDAP first; for TLDs without RDAP it follows the IANA referral to the right WHOIS server and shows the raw response too.
Redacted data
Since GDPR, most registries redact personal registrant data. Seeing “redacted” is normal and doesn't make a domain suspicious.
Domain age
Domains only days or weeks old are common in phishing and fraud campaigns. Checking the age of an unknown sender's domain is a quick risk signal.
Frequently asked questions
Why can't I see the owner's name?
Registries and registrars don't publish personal data under privacy regulations. With a legal basis you can request it from the registrar.
What is a transfer lock?
The clientTransferProhibited status stops the domain from being moved to another registrar without your approval. It should always be on for business domains.
What happens if my domain expires?
After a short grace period the domain is released and anyone can register it. Attackers buy expired domains to capture email traffic.
I entered a subdomain — why are results for the parent?
WHOIS records exist only for the registered domain; subdomains have no separate registration.
