Lookups run on our server via RDAP first, then classic WHOIS as a fallback. Contact details are often redacted by registries (GDPR). Results are cached to keep the tool fast.
How do you read WHOIS results?
A WHOIS record shows a domain's registrar, creation and expiry dates, nameservers, and status codes. Since GDPR, most registrant contact details are redacted behind a privacy service. The registration date and the nameservers are usually the two genuinely useful fields.
