Check domain registration status, expiry date, registrar, and availability instantly via direct RDAP registry queries. The modern successor to WHOIS.
The Registration Data Access Protocol — the modern replacement for WHOIS
Unlike WHOIS (plain text, inconsistent), RDAP returns structured JSON data that is easy to parse and machine-readable. Defined by IETF RFC 9083.
RDAP queries the authoritative registry server directly — Verisign for .com/.net, PIR for .org, Identity Digital for 200+ new TLDs. Data comes straight from the source.
Active domains show “clientTransferProhibited”. Expiring domains enter “redemptionPeriod” then “pendingDelete”. A 404 response means the domain has dropped and is available for registration.
What each domain status means and what action to take
DA.N tracks thousands of expiring domains 24/7. Create filters, save searches, and track domains in your niche.
