🌐 Free WHOIS Lookup — Instantly Check Who Owns Any Domain

Want to know who registered a website, when it was created, when it expires, or which company controls it? Our free WHOIS lookup tool gives you all of that — instantly, for any domain name in the world.

What is WHOIS?

WHOIS (pronounced "who is") is a public internet protocol that stores registration information for every domain name on the web. Think of it as the public record of domain ownership — similar to how real estate ownership is a matter of public record.

When someone registers a domain like example.com, their information is stored in a WHOIS database maintained by the domain's registry (such as Verisign for .com domains). This database is publicly accessible and reveals details like the registrar, creation date, expiration date, name servers, and contact information.

Today, most domain owners activate WHOIS Privacy Protection, which replaces personal data with a proxy. Our tool shows exactly what the registry has on file — including when privacy is enabled.

What it does What This Tool Shows You

📅
Important Dates
Creation date, last update, and expiration date — with a countdown showing how many days until the domain expires.
🏢
Registrar Info
The company where the domain was registered (e.g. GoDaddy, Namecheap, Porkbun), their IANA ID, abuse contacts, and WHOIS server.
🌍
Domain Age
See exactly how old a domain is — whether it's a brand-new site or an established presence that's been online for years.
🔒
DNSSEC Status
Find out if the domain has a cryptographic chain of trust enabled, protecting it from DNS spoofing attacks.
🖥️
Name Servers
The authoritative DNS servers that control where the domain points — revealing if it uses Cloudflare, AWS, Google, or a custom setup.
📋
Domain Status Codes
EPP status codes like clientTransferProhibited or serverHold — with plain-English explanations of what each one means.

Why Use It Who Uses WHOIS — and Why

🕵️
Verify a website before you trust it. Is a site only 2 weeks old but claiming to be an established business? WHOIS will tell you.
💼
Research a domain before buying it. Check when it expires, its full history, and who the current registrar is before making a purchase offer.
🛡️
Spot phishing and scam sites. Fraudulent sites are almost always very newly registered. A domain created last week impersonating a bank is a huge red flag.
🔧
Troubleshoot DNS issues. Developers and sysadmins use WHOIS to verify name servers, check DNSSEC configuration, and diagnose propagation problems.
📰
Journalism and research. Reporters and security researchers use WHOIS to trace the ownership of websites involved in misinformation, fraud, or cyberattacks.

⚙️ How It Works — Powered by RDAP

Unlike outdated WHOIS tools that scrape plain-text responses, our tool uses RDAP (Registration Data Access Protocol) — the modern, structured replacement for the old WHOIS system. RDAP is the official standard maintained by IANA (the Internet Assigned Numbers Authority) and returns clean, reliable, structured data for over 1,500 TLDs.

We query the IANA Bootstrap registry to automatically find the correct RDAP server for any TLD, then fall back to multiple secondary sources if needed — so you always get results, even for obscure domain extensions.
