Free WHOIS lookup (RDAP)

WHOIS lookup: who registered a domain, when, and when it expires

Enter up to five domains and read each one's registrar, created and expiry dates, name servers, EPP status, DNSSEC and hosting from the registry's RDAP record. Same engine as our domain age checker; no WHOIS reseller and no sign-up.

One domain per line, up to 5 at a time. No sign-up.

Answers come straight from each domain's registry, so they match what the registry holds today.

WHOIS lookup

What WHOIS is, and why this page uses RDAP instead.

WHOIS is the public registration record for a domain name: who holds it, through which registrar, when it was created, when it expires, which name servers point DNS at, and which EPP status codes apply. Investigators, buyers, SEOs and abuse teams use it to verify ownership context, spot expiring names and see whether a domain is locked or in redemption.

For generic top-level domains (.com, .net, .org and others), ICANN required registries to retire the old port-43 WHOIS protocol in January 2025. The replacement is RDAP (Registration Data Access Protocol): HTTPS and JSON from each registry's own server. MrKeyword finds the right registry through IANA's bootstrap file and reads that RDAP answer, so every date and status you see is what the registry holds today.

Domain status

EPP status codes in plain English.

clientTransferProhibited — the registrar locked the domain against transfer. Common on names the owner wants to keep; remove the lock at the registrar before moving registrars.

serverHold — the registry suspended the domain at the registry level. DNS usually stops resolving until the hold is lifted.

redemptionPeriod — the name expired and the registrar may still restore it for a fee before it is deleted.

pendingDelete — the registry is about to drop the name; it is no longer restorable through normal renewal.

Other statuses follow the same pattern: client means the registrar set it, server means the registry set it. This tool lists every status the RDAP record returns, with a one-line explanation beside each.

Privacy

Why registrant names are redacted, and how to contact an owner.

Full WHOIS used to show a registrant's name, address, phone and email. GDPR and registry privacy policies now redact that contact data in public RDAP and WHOIS output. You still see the sponsoring registrar, technical facts and status codes.

To reach a redacted owner, use the registrar shown in the result: every ICANN-accredited registrar maintains abuse and contact channels. For trademark or phishing issues, the registrar's abuse form is the supported path; this tool does not guess private email addresses.

How to use the lookup

Three steps to the registry's RDAP record.

  1. Enter up to five domains

    With or without https:// or www. Subdomains are trimmed to the registered domain.

  2. Read registrar, dates and status

    Created, expires, last changed, registrar (and IANA id when published), name servers, EPP statuses with plain-English notes, DNSSEC and live hosting.

  3. Compare or share

    Put competitors side by side, then copy a link that re-runs the same domains.

How the numbers are made

Where every field comes from.

RDAP at the registry that holds the domain.

IANA RDAP bootstrap

IANA publishes which HTTPS RDAP server answers for each TLD. MrKeyword asks only those servers.

Registry RDAP JSON

Registrar, events (created, expires, last changed), name servers, status and DNSSEC are parsed from the registry's domain object.

No reseller cache

When a registry publishes no RDAP or returns an error, the result says so instead of showing stale WHOIS text.

A few useful boundaries

What this does not do

Registration facts are from the registry. Contact details are not.

Registrant name, email, phone and street address are not shown.

Registries redact them; RDAP may omit or mask those entities entirely.

Some country registries still publish limited or no RDAP.

Those domains may return a clear error instead of guessed dates.

Hosting is a live DNS lookup

beside the registry record; it can change independently of WHOIS.

FAQ

Questions about WHOIS and RDAP.

Get started free
Is WHOIS lookup free?

Yes. Look up up to five domains at once with no account. Each answer comes from the domain's registry over RDAP, the official successor to port-43 WHOIS for generic domains, and you can share the result with a link.

Why is the owner hidden?

Registries redact registrant name, address, phone and email in public records. GDPR and ICANN privacy rules treat that data as personal. You still see registrar, dates, name servers and status; to reach the owner you use the registrar's abuse or contact form.

WHOIS vs RDAP?

WHOIS was the old text protocol on port 43. ICANN required gTLD registries to sunset it in January 2025 in favour of RDAP, a structured JSON API over HTTPS. This tool reads RDAP, so you get the same registration facts in a consistent format.

How do I find when a domain expires?

Enter the domain above. The registry's RDAP record includes an expiration event; this page shows it as the expiry date and how many days remain. Renew before that date or the name can enter redemption and pending delete.

What does clientTransferProhibited mean?

It is an EPP status set by the registrar: the domain cannot move to another registrar until the lock is removed. It is common on domains the owner wants to keep, and it does not stop DNS or the website from working.
