WHOIS Lookup

Look up the registration record for any domain name. Enter a domain below to see its registrar, creation and expiry dates, last update, status codes and name servers — alongside the full raw WHOIS (or RDAP) response.

How to use it

  1. Type a bare domain name (for example example.com) into the field above — no http:// and no path.
  2. Press Look up. The tool queries the domain's authoritative WHOIS server over port 43.
  3. Read the summary table for registrar, dates, status and name servers, and scroll the raw record for the full response.

Why use it

A WHOIS lookup tells you who manages a domain, when it was registered, and — critically — when it expires, so you can catch lapsing domains before they drop. Developers and SEOs use it to verify ownership during migrations, audit a competitor's domain history, confirm name server changes, and spot domains nearing renewal. This tool runs server-side and automatically falls back to RDAP when a registry blocks classic WHOIS, so you get an answer either way.

Frequently asked questions

What is WHOIS?
WHOIS is a public directory protocol that returns registration details for a domain name — who registered it, when it was created and when it expires, the registrar of record, the domain status codes and the authoritative name servers. This tool queries the registry over port 43 and parses the response for you.
What is RDAP and why might results look different?
RDAP (Registration Data Access Protocol) is the modern, JSON-based successor to classic WHOIS. When a registry blocks or rate-limits port 43, this tool automatically falls back to RDAP, so you still get the same structured fields. The raw output block will show JSON instead of plain WHOIS text in that case.
Why are some contact details missing or "redacted"?
Since GDPR took effect, most registrars redact personal registrant data (name, email, address) from public WHOIS and RDAP records. Registrar, dates, status and name servers remain public, but owner contact fields are usually hidden behind a privacy or "REDACTED FOR PRIVACY" notice.
