WHOIS Lookup
Check who holds a domain, when it expires, and what it would cost to register.
Records are read live from the authoritative registry over RDAP, the IETF protocol that replaced WHOIS. We show only the fields the registry actually publishes — nothing is estimated or filled in by us, and registrant contact details are withheld by registries for privacy.
What you get
- Registrar — the company the domain is registered through, with its IANA ID where the registry publishes one.
- Registration and expiry dates — as recorded by the registry, not inferred.
- Nameservers and EPP status codes — which tell you where the domain is hosted and whether it is locked against transfer.
- Registrar prices for that extension — read from each registrar’s own published price list. Extensions we have not captured say so rather than showing an estimate.
If a domain has no record
A registry returning no record usually means the name is unregistered — but it is not a guarantee. Names can be reserved, premium-priced or blocked by the registry, and a few registries do not answer these queries at all. Confirm at the registrar before you rely on it. Where we cannot reach a registry we say so plainly instead of guessing, because an unverified domain is not the same as an available one.
Checking more than one
The bulk checker runs the same live lookup across a list of domains at once. Looking for every domain owned by one person or company instead? That is reverse WHOIS, and we explain here why no one can offer it for free.
