Domain WHOIS Lookup — RDAP, Expiry, DNS, MX & SSL in Bulk

Look up thousands of domains at once and get the registrar, creation date, expiry date and days to expiry, domain age, status, nameservers and DNSSEC, plus the registrant when it is public (for .br domains, the owner's name and CNPJ/CPF). Uses RDAP, the official successor of WHOIS, with a classic WHOIS fallback for registries that don't offer RDAP.

Optionally adds DNS (A, AAAA, MX, NS, SPF, DMARC and the detected email provider: Google Workspace, Microsoft 365, Zoho...) and the SSL certificate (issuer, validity, days to expiry, names covered).

Built for domain portfolio and expiry monitoring, lead enrichment (which companies use Google Workspace or Microsoft 365), security and IT audits, and SEO research.

Why this one

• Domains, URLs or emails as input: the domain is extracted automatically, subdomains are reduced to the registered domain.
• Registrar lookup for .com/.net: the central registry only knows the registrar, so the actor also asks the registrar for the registrant organization and country.
• Days to expiry for both the domain and the SSL certificate, ready for alerts.
• Email provider detection from MX records, plus SPF and DMARC.
• .br registrant with CNPJ, straight from registro.br.

Notes

• Most registrars hide personal registrant data (GDPR); companies often keep their organization name public.
• Some country registries (e.g. .de) publish only whether a domain is registered.
