WHOIS Domain Lookup

Look up registration details, registrar, nameservers, and expiration dates for any domain name. Instant and free.

What Is a WHOIS Lookup?

Every domain name registered on the internet has a public record in the WHOIS database. This record contains the registrar that manages the domain, the registration and expiration dates, the nameservers pointing to the hosting provider, and, unless privacy protection is enabled, the registrant contact information. WHOIS data is maintained by domain registries and is the authoritative source for domain ownership information.

WHOIS lookups are essential for verifying domain ownership before a purchase or transfer, investigating suspicious websites, checking domain expiration dates, finding the registrar to manage DNS settings, and identifying who is responsible for a domain involved in abuse or spam. Our tool connects directly to official WHOIS servers on port 43 for accurate, real-time results.

How to Read WHOIS Results

WHOIS records contain several key fields. The Registrar is the company where the domain was registered (e.g., GoDaddy, Namecheap, eNom). The Creation Date shows when the domain was first registered. Older domains generally have more authority with search engines. The Expiry Date tells you when the registration expires and needs to be renewed. If it lapses, the domain becomes available for anyone to register.

The Name Servers indicate where the domain's DNS is hosted. This tells you which hosting provider or DNS service is managing the domain's records. The Domain Status codes like "clientTransferProhibited" show what restrictions are in place on the domain. If you see "Registrant" information showing a privacy service instead of a person's name, it means the domain owner has enabled WHOIS privacy protection.

Frequently Asked Questions

  • What is a WHOIS lookup used for?
    WHOIS lookups are used to find out who owns a domain, when it was registered, when it expires, which registrar manages it, and what nameservers it uses. It's an essential tool for domain research, purchase negotiations, abuse investigations, and DNS troubleshooting.
  • Why does WHOIS show a privacy service instead of the owner?
    Most domain registrars offer WHOIS privacy protection that replaces the registrant's personal contact details with a proxy service. This is legal, common, and recommended. It prevents spam, unwanted solicitations, and identity theft. The actual owner can still be reached through the privacy service if there's a legitimate reason.
  • Is this tool free to use?
    Yes, completely free with no signup, no account, and no limits for normal use. Look up any domain as many times as you need.
  • Which domain extensions are supported?
    We support over 100 TLDs including .com, .net, .org, .info, .biz, .co, .io, .us, .uk, .de, .fr, .au, .ca, .eu, .ru, .jp, and many more. If your extension isn't supported, try a more common TLD or use the ICANN WHOIS service directly.
  • How accurate is the data?
    Our tool queries official WHOIS servers directly over port 43 in real time, the same servers that registrars and ICANN use. The data is as current as the registry's database, which is typically updated within minutes of any change.
