WHOIS Lookup

See who registered a domain, and when it expires.

The domain or address you enter is sent to UtilSlate’s server, which asks the registry’s RDAP service (and the registrar’s). Nothing is stored.

What you get

  • Dates and expiry
  • Registrar and servers
  • IP networks too

Questions

What is RDAP, and is it the same as WHOIS?

RDAP (Registration Data Access Protocol) is the registries’ modern replacement for WHOIS: the same registration data, in a structured form. Since 2025 it is the official source for generic domains like .com and .org. This tool asks the registry and, when the registry points to it, the registrar.

Why is the owner’s name hidden?

Since privacy laws like the GDPR, registrars hide personal details of domain owners and show “redacted for privacy”. Companies sometimes show their name. To reach an owner, registrars usually offer a contact form or an anonymised email.

Why does it say it can’t look up my domain?

Some country-code registries (for example several European ones) don’t offer RDAP yet, only the old WHOIS service or their own website. The page says so when that’s the case.

What do the status codes mean?

“Transfer prohibited”, “update prohibited” and “delete prohibited” are normal locks against unwanted changes. “Pending delete” or “redemption period” mean the domain has expired and is on its way to being released.

Is it free? Do I need an account?

It is free to use and there is nothing to sign up for. There are no watermarks and no daily limits.
