RDAP & WHOIS Domain Intelligence
Look up current public domain registration data through RDAP, including lifecycle events, statuses, nameservers, DNSSEC and raw authoritative JSON.
What Is the RDAP & WHOIS Domain Intelligence?
A modern public domain-registration lookup client based on RDAP, the structured successor to legacy WHOIS for generic top-level domains. It shows registry identifiers, lifecycle dates, EPP-style statuses, nameservers, DNSSEC delegation and service notices while preserving the raw JSON response.
How It Works
Enter a registered domain such as example.com and run the lookup. BrowserTools contacts rdap.org, which discovers or redirects to the appropriate public registry or registrar RDAP service. Review the summarized record and download the exact JSON.
When to Use It
Check domain lifecycle signals, delegation details and publicly disclosed registration data. Redaction, policy and registry implementation determine what appears; results are not proof of ownership, identity, availability or reputation.
Frequently Asked Questions
- Why RDAP Instead Of Port 43 WHOIS?
- RDAP returns standardized, internationalized, secure JSON over HTTPS and is now the definitive registration-data service for gTLDs, while legacy WHOIS obligations were phased out in 2025.
- Does It Show Private Registrant Data?
- Only information returned publicly by the authoritative RDAP service is displayed. Privacy law and policy often redact contact data.
- Is This Lookup Entirely Offline?
- No. The queried domain is sent to rdap.org and the applicable registry or registrar service. Nothing else from the page is required for the request.
