WHOIS Domain Lookup: what it is for
Enter a .com, .net, .org or other domain and see the public registration data from the official RDAP lookup, which replaced WHOIS: creation and expiry dates, domain age, days until expiry, registrar, abuse contact, DNS servers, security locks explained in plain words and DNSSEC. The timeline shows the registration period up to expiry. If the domain isn't registered, the tool tells you it is available.
Because of privacy laws like the GDPR, the registrant's personal data is usually hidden.

Frequently asked questions
What is WHOIS?
It is the public lookup of a domain's registration data: creation and expiry dates, the registrar, the DNS servers and the status. Today the official lookup uses the RDAP protocol, which replaced the old WHOIS and returns better-organized data.
Why isn't the owner's name shown?
Because of privacy laws like the GDPR, most registries hide the registrant's name, email and phone. Usually only the registrar and sometimes organization names appear.
How do I know if a domain is available?
If the lookup says the domain is not registered, it is probably free. Confirm with a registrar first, because recently deleted domains may spend a few days in quarantine.
What do statuses like clientTransferProhibited mean?
They are security locks. Transfer prohibited stops the domain from being moved to another company without authorization, delete prohibited stops it from being deleted and update prohibited stops changes. Having these locks is a good sign.
Is it really free?
Yes, 100% free. No sign-up, no subscription and no usage limits. All Tools123 are free.
