How it works

The server queries the authoritative RDAP service for the domain’s TLD (or the regional internet registry for IPs), falling back to WHOIS where RDAP is unavailable.

Frequently asked questions

Why is the owner information hidden?

Most registrars redact personal registrant data for privacy and GDPR compliance. Registrar, dates and name servers remain visible.

What is RDAP?

The Registration Data Access Protocol is the structured, standardized successor to WHOIS.
