Domain Whois (RDAP) Lookup

Look up who a domain is registered through, when it was registered and when it expires — straight from the registry.

{ } How to use

  1. Enter the domain.
  2. Select Process.
  3. Copy any value you need — each row has its own copy button.

{ } How it works

Domain Whois (RDAP) Lookup works on the text you provide. Select Process ▸ and it runs entirely in your browser — nothing is uploaded to a server — then shows the result in the Output panel.

Input

  • Domain — paste or type your input in the left panel (use Sample for an example)

Output

TXT text — copy or download it from the Output panel.

{ } Common uses

  • Check when a domain expires before it lapses.
  • Find out which registrar holds a domain, so you know where to transfer it from.
  • Confirm the name servers a registry has on record match the ones actually answering.
  • See whether a domain is locked against transfer or deletion.

{ } Limitations

  • Registrant names, addresses and email are no longer published. Registries removed them for privacy reasons, so the classic whois record most people remember no longer exists — what you see here is everything that remains public.
  • A few registries do not allow their records to be read from a web page, and some country-code domains publish no RDAP at all. Those cannot be looked up from a browser by anyone, and the tool says so rather than showing an empty result.

{ } FAQ

Is my data uploaded to a server?

No. Everything runs locally in your browser — your files never leave your device.

Can I process more than one file at once?

This tool works on one input at a time.

Is this tool free?

Yes — it’s completely free and needs no sign-up.

Is this the same as whois?

It is the modern replacement for it. Classic whois runs over a raw TCP connection that a browser cannot open, and returns free text that every registry formats differently. RDAP is the official successor: same data, over HTTPS, in a structured form — which is also why this tool can exist in a browser at all when a whois client cannot.

Why is the registrant’s name missing?

Because registries stopped publishing it. Contact details were removed from public records for privacy reasons, and are now shown only to parties with a legal reason to see them. No lookup tool, this one included, can show what the registry does not publish.

Is my lookup private?

Your query is sent to a public DNS resolver to answer it. No files are involved and nothing is stored.

Why might results differ from my computer?

Resolvers cache records for the record’s TTL, so a very recent change can take time to appear everywhere. Use the DNS Propagation tool to compare resolvers.
