WHOIS search for ownership, expiry, and registrar details

Use this WHOIS tool to check whether a domain is available, identify registrar data, and review registration and expiration timelines. It is designed for renewals, transfer planning, and incident response when ownership history matters.

For deeper DNS verification, continue to DNS Lookup or run DNS Propagation Check to compare resolver behavior worldwide.

How to read a WHOIS result

Four fields answer most questions. Registrar tells you which company manages the registration, which matters when you need to renew, transfer, or recover a domain. Creation and expiry dates show the domain's age and how long until it lapses; an expiry inside the next 60 days deserves immediate attention because most registrars lock transfers for 60 days after certain changes. Nameservers reveal where the DNS is actually hosted, and a mismatch between the WHOIS nameservers and what you expected is a classic sign of an incomplete migration. Status codes like clientTransferProhibited are normal protective locks, while serverHold or clientHold means the registry has suspended the domain and it will not resolve.

Expect redaction on personal fields. Since GDPR, most registries replace the registrant's name, address, and email with "REDACTED FOR PRIVACY" or a proxy service. That is normal and does not indicate anything shady. The registrar, dates, nameservers, and status codes stay public, and those are the fields that drive real decisions.

Quick FAQ

Can WHOIS show private registrant data? Many registries mask personal fields, but you can still verify registrar, status codes, and key dates.

The expiry date passed but the site still works. Why? Most registrars grant a renewal grace period of roughly 30 days, followed by a redemption period with a steep recovery fee. The domain often keeps resolving during grace, so never treat a working site as proof the registration is safe.

Should I rely on one source only? No, combine WHOIS output with DNS and SSL checks before making migration or security decisions.

What is the difference between WHOIS and RDAP? RDAP is the structured, JSON-based successor to the old WHOIS text protocol. This tool queries both where available, so you see registry-authoritative data instead of a possibly stale registrar mirror.
