Whois Lookup

Free whois lookup for registrar, creation/expiry dates, status and DNS servers

What is a Whois lookup?

A domain Whois lookup is a free tool for viewing a domain's public registration data: registrar, creation and expiry dates, domain status, DNS servers and more. It uses RDAP (Registration Data Access Protocol) — the modern standard replacing Whois — to fetch authoritative data directly from each registry.

How to use

Enter a domain (e.g. example.com) in the input box and click Look up. The tool automatically strips http://, www. prefixes and lowercases it.

Results are shown field by field: domain, status, created/updated dates, expiry, DNSSEC, registrar, registrant and DNS servers. Click the copy button next to any field to copy it.

About RDAP

RDAP is the structured JSON replacement for Whois, mandated by ICANN since 2018. This tool routes to the correct registry's RDAP server via the rdap.org bootstrap service.

Common uses

  • Check whether a domain is registered and when it expires
  • Confirm a domain's registrar and status
  • Brand protection and domain ownership research
  • Troubleshoot DNS server configuration

Frequently Asked Questions

What is Whois?+
Whois is the protocol for looking up domain registration data. This tool uses its modern standard, RDAP, to return the registrar, creation/expiry dates, domain status and DNS servers.
Why can't I see the registrant's name and email?+
Since the GDPR took effect in 2018, most registrars redact the registrant contact details of personal domains. Only the registrar, dates, status and DNS servers remain public.
Which TLDs are supported?+
Via the rdap.org bootstrap service, most gTLDs (.com, .net, .org, .io and more) and many ccTLDs (.cn, .jp, .de, .uk and more) are supported. A few TLDs without RDAP may return partial data.
How fresh is the data?+
RDAP queries each registry's authoritative data source directly, returning real-time (or registry-cached) information.
Is it free and safe?+
Completely free. Your browser queries the public RDAP service directly; domain registration data is public information, with no sign-up or API key required.
