Free WHOIS & RDAP Lookup Tool

Query official domain registration records, registrar details, registration lifecycle status, and DNS nameservers.

WHOIS & RDAP Domain Lookup

Inspect domain registration details, registrar status, expiry dates, nameservers, and domain privacy status.

How WHOIS & RDAP Lookups Work

Queries authoritative registry data to check domain ownership lifecycle, expiration countdowns, registrar transfer locks, and authoritative nameservers before catastrophic domain lapses occur.

✓ Expiration Countdown & Auto-Renew Health

Healthy: > 60 days remaining with active registrar auto-renew.
Warning (< 30 days): Remind the client immediately. Expired credit cards on client registrar accounts are the #1 cause of sudden client website outages.

🔒 Domain Status: Transfer Lock (clientTransferProhibited)

Protected: The domain is locked against unauthorized transfer requests or domain hijacking.
Unlocked (Active / OK): Anyone with compromised client email credentials can initiate a transfer.

Frequently Asked Questions About WHOIS & Domain Registration

What is the difference between legacy WHOIS and modern RDAP?+
Legacy WHOIS operates over port 43 and returns unstructured plain text that varies wildly across registrars. RDAP (Registration Data Access Protocol) is ICANN's modern replacement that operates over HTTPS and returns standardized, machine-readable JSON data with enhanced security and privacy controls.
Why are domain owner names and contact details redacted in WHOIS?+
Following global privacy regulations like the EU's GDPR and California's CCPA, ICANN requires domain registrars to mask personal contact information (name, home address, personal phone number) behind privacy proxy services unless explicit consent is provided.
What does "clientTransferProhibited" mean in domain status?+
This status code (Registrar Lock) indicates that the domain cannot be transferred to another registrar without the owner first logging into their registrar control panel to explicitly unlock the domain. It is an essential security measure against domain hijacking.
How do I know when my domain expires?+
Our WHOIS lookup tool parses the registry expiration date (registryExpiryDate / Expiration Date) and calculates an active countdown showing exactly how many days remain before the domain enters the renewal grace period or redemption window.
