WHOIS Lookup

What It Does

Queries RDAP servers to retrieve domain registration metadata including registrar name, IANA accreditation ID, and URL; registration dates (created, updated, expires) with computed domain age in days, newly-registered flag (< 30 days), days until expiry, and expiring-soon flag (< 30 days); EPP status codes (clientTransferProhibited, serverHold, redemptionPeriod, etc.); authoritative nameservers; DNSSEC signing status; and registrant, administrative, and technical contacts — each with name, organization, email, phone, and full address (street, city, state, postal code, country). Handles GDPR-redacted registrant data gracefully and supports RDAP bootstrap discovery for both gTLDs and many ccTLDs. Optionally returns the full raw RDAP response via the include_raw parameter.

Why It's Useful

With WHOIS officially deprecated, RDAP is the only reliable source for gTLD registration data. EdgeDNS handles RDAP bootstrap discovery automatically — essential for due diligence, brand protection, phishing detection, and competitive research. Assess domain age, trustworthiness, and identify potential typosquatting domains.
