WHOIS LOOKUP

Free WHOIS
domain lookup.

See who a domain is registered with, when it was created and when it expires,
and its status, straight from the registry.

A domain or full URL. Subdomains are looked up through their registered domain. Live DNS lookup

Your browser sends the domain you search directly to Google Public DNS, RIPEstat, and the domain’s registry to fetch public records. We don’t store your searches on our servers.

CURIOUS? TRY

One domain. The bigger picture.

Hosting, registrar, expiry, DNS records, email, and security details appear here.

PUBLIC DATA. ONE SIMPLE LOOKUP.
THE SHORT VERSION

WHOIS and RDAP, explained

WHOIS is the traditional way to find out who a domain is registered with. Registries are replacing it with RDAP, which returns the same registration data in a structured, more reliable format. WhoHostsIt reads the RDAP record directly from the domain’s registry.

Since GDPR, most registrars hide the owner’s name, email, and address. You’ll still see the registrar, key dates, status codes, and nameservers, plus the registrar’s abuse contact for reporting problems.

Common questions

Who owns this domain?

If the owner chose to publish their details, they appear in the Registration section. Most personal details are now redacted for privacy; to reach the owner, use the registrar’s contact form or abuse address.

What do status codes like clientTransferProhibited mean?

They are locks set by the registrar or registry. clientTransferProhibited stops the domain being moved to another registrar until the owner unlocks it, which protects against theft. redemptionPeriod and pendingDelete mean the domain has expired.

Why is the WHOIS information missing?

Some country-code registries, such as .de and .io, don’t offer a public RDAP lookup. For those, use the registry’s own WHOIS website.
