WHOIS Lookup

Look up any domain: who it's registered with, when it expires, where its DNS is hosted, and what its status means.

Works for .com, .ca, .ae, .sa and most other domain endings. Enter a website address or email and we'll use its domain.

Registration data from RDAP via rdap.org and the domain's registry.

Lookups go from your browser to rdap.org and the domain's registry. When a registry has no RDAP service, the lookup runs through Neu Notion's server, which caches the result briefly but doesn't log it. Only anonymous usage counts are kept.

How the WHOIS lookup works

The lookup first uses RDAP, the modern replacement for WHOIS, which returns structured data straight from the domain's registry. For domain endings whose registry doesn't offer RDAP yet, including several country codes, it falls back to the registry's classic WHOIS server through Neu Notion's website.

You'll see who the domain is registered with, when it was registered and when it expires, where its DNS is hosted, whether DNSSEC is on, and what its status codes mean. Most registries now hide the owner's personal details for privacy, so the registrant usually shows as hidden.

Why can't I see who owns a domain?

Since GDPR, most registries and registrars hide registrants' personal details. You'll usually see only the registrar, and sometimes the organisation and country. To contact the owner, use the registrar's contact form or abuse address.

What happens when a domain expires?

Most domains stop working at expiry, then enter a grace period of about 30 to 45 days when the owner can still renew normally. After that comes a redemption period with a higher fee, and finally deletion, when anyone can register it.

What does clientTransferProhibited mean?

It's a transfer lock set by the registrar to stop the domain being moved to another registrar without permission. It's normal and recommended. Unlock it at your registrar only when you want to transfer the domain.

What is RDAP?

RDAP (Registration Data Access Protocol) is the standard that replaced WHOIS for generic domains like .com. It returns structured, consistent data over HTTPS, while WHOIS returned free-form text that differed between registries.
