Frequently Asked Questions

Why is RDAP superior to legacy WHOIS?

RDAP is the official IETF/ICANN successor to port 43 WHOIS. It delivers structured, standardized JSON responses, internationalized domain support, and reliable uptime.

Why are personal details redacted in RDAP results?

In compliance with GDPR and international privacy regulations, ICANN registrars redact personal registrant contact details (name, home address, personal phone) by default.

What happens after a domain name expires?

Expired domains do not drop instantly. They enter an Auto-Renew Grace Period (30-45 days), followed by a Redemption Period (30 days), and a 5-day Pending Delete phase before becoming available to the public.
