Free WHOIS Lookup

Who owns that domain, and when does it expire? NToolHub's WHOIS Lookup page is upfront: browsers can't speak the WHOIS protocol — so instead of a fake result, you get the exact terminal commands plus one-click links to ICANN Lookup, who.is and RDAP JSON endpoints. Real registrar data, zero pretense.

ℹ️
Why no live result here? WHOIS runs over a raw TCP protocol (port 43) that browsers cannot speak, and most WHOIS web APIs block cross-site requests. Instead, this tool builds the exact commands and one-click lookup links you need — everything runs from your own terminal or trusted lookup services.
Private by design. This page performs no live network lookups and uploads nothing — it only generates commands and links that run on your own machine or on trusted lookup sites you open yourself.

How to Use the WHOIS Lookup

  1. Enter the domain you want to investigate.
  2. Click Get WHOIS Lookup Links.
  3. Use the terminal command or open ICANN Lookup / who.is in a new tab.
  4. Look for the registrar, creation date and name servers in the record.

Features

Enter any domain to generate whois and RDAP curl commands for your terminal, plus direct links to ICANN's official lookup, who.is reports and machine-readable RDAP JSON — with a note on GDPR-redacted records.

Benefits & Use Cases

You reach authoritative registrar data in one click instead of hunting through ad-heavy lookup sites, and the terminal commands give you scriptable access for bulk or repeated checks.

Tips

Look for registrar, creation/expiry dates and name servers; expect personal data to be redacted for most TLDs since GDPR; use RDAP JSON when you need machine-readable output.

Frequently Asked Questions

Why doesn't this page show WHOIS results directly?

WHOIS runs over raw TCP port 43, which browsers can't access, and WHOIS web APIs block cross-origin requests. Rather than fake a result, this tool gives you the real commands and official lookup links.

What is RDAP?

The Registration Data Access Protocol — WHOIS's modern, JSON-based successor. It returns structured, machine-readable domain data over HTTPS.

Why is the owner's name hidden?

Since GDPR, most registries redact personal data from public WHOIS. You'll typically still see the registrar, dates and name servers.

How do I find when a domain expires?

Run the whois command or open ICANN Lookup from this tool and look for 'Registry Expiry Date' — set a renewal reminder well before it.
