WHOIS lookup with red flags

Structured registration data for any domain, plus the signals that matter for spotting a malicious one.

Free and anonymous. No account required.

What this checks

This returns RDAP registration data (created/updated/expires dates, registrar, registrant, statuses, nameservers) and a red-flags list.

Why it matters

WHOIS context, especially registration age and privacy redaction, helps you judge whether a sending domain is trustworthy.

How the detection works

A live RDAP query via rdap.org returns structured records; a deterministic rule set surfaces red flags like recent registration or privacy protection.

FAQ

Why is the registrant redacted?

Most registrars enable WHOIS privacy by default since GDPR. Redaction alone is not suspicious, but combined with a young domain it is worth noting.

Is RDAP the same as WHOIS?

RDAP is the modern, structured replacement for the legacy WHOIS protocol. It returns the same kind of data in JSON.
