WHOIS Lookup
Check domain registration details, expiry date, nameservers, and registrar info for any domain.
Queries the official WHOIS database and returns registrar, creation date, expiry date, nameservers, and status codes for the domain.
What Is WHOIS and Why Does It Matter?
WHOIS is a query-and-response protocol that has been part of the internet's infrastructure since the early 1980s. When a domain name is registered, the registrar records a set of details — who registered it, when, through which company, and when the registration expires — and publishes that record in the WHOIS database. Anyone can query that database to look up the registration information for a domain. This transparency is what makes the domain name system accountable and traceable.
For website owners, system administrators, and security researchers, WHOIS data is an indispensable diagnostic tool. It tells you whether a domain is still registered, when it is due to expire, which registrar controls it, and which nameservers are authoritative. If you are investigating a suspicious website, researching a domain before purchasing it, or simply trying to remember which registrar you used for a long-forgotten project, a WHOIS lookup gives you the answers in seconds. It is also the first place to look when troubleshooting DNS issues, because the nameservers listed in WHOIS must match the ones you have configured.
Privacy has reshaped how WHOIS works in recent years. Following the introduction of GDPR, most registrars now redact personal contact information by default, replacing it with proxy details or generic privacy notices. Many registrars also offer paid or free WHOIS privacy services that hide your name, email, and phone number from public queries. Even with privacy enabled, the registrar name, creation date, expiry date, nameservers, and status codes remain visible, which is usually enough for technical troubleshooting. This free WHOIS lookup tool retrieves those public fields for any domain.
How to Use the WHOIS Lookup
- Enter your domain name (for example,
example.com) into the input field. You do not need to include thehttps://prefix; the tool strips it automatically. - Click the Lookup button. The tool queries the relevant WHOIS server for the domain's registration record.
- Review the registration details, including registrar, creation date, expiry date, nameservers, status codes, and any available registrant information.
Key WHOIS Fields Explained
A WHOIS record contains several fields, each serving a different purpose. The five fields below are the ones you will rely on most when diagnosing domain issues or planning a renewal.
Registrar
The company that registered the domain on behalf of the owner. The registrar manages billing, renewals, and transfers. Knowing your registrar is the first step in any account or renewal task.
Creation Date
The date the domain was first registered. Useful for verifying the age and history of a domain, assessing credibility, or confirming that a recent registration has propagated.
Expiry Date
The date the current registration period ends. If you do not renew before this date (plus any grace period), the domain becomes available for others to register. Always monitor this field.
Nameservers
The DNS servers authoritative for the domain. These must point to the provider where you manage your DNS records. A mismatch here is a common cause of DNS resolution failures.
Domain Status
Status codes such as clientTransferProhibited or serverDeleteProhibited indicate locks and restrictions. A locked domain cannot be transferred or deleted, which protects against unauthorized changes.
Frequently Asked Questions
What is WHOIS privacy protection?
WHOIS privacy replaces your personal contact information (name, email, phone) with the privacy service's details. This prevents spam and protects your identity. Most registrars offer it free or for a small fee.
How do I find when my domain expires?
Use this WHOIS lookup tool and check the "Expiry Date" field. Most registrars also show the expiry date in your account dashboard. Enable auto-renew to avoid accidental expiration.
Can I hide my WHOIS information?
Yes. Enable WHOIS privacy protection through your registrar. Under GDPR, European registrants have their personal data automatically redacted from WHOIS. Some TLDs (like .us) do not allow privacy protection.
What is a domain grace period?
After a domain expires, most registrars offer a grace period (typically 0-45 days) during which you can renew at the normal price. After that, there's a redemption period (30 days) with a higher fee. After redemption, the domain becomes available for public registration.
How do I transfer my domain to another registrar?
Unlock the domain at your current registrar, obtain the auth/EPP code, initiate the transfer at the new registrar, and confirm via email. Transfers typically take 5-7 days. Some TLDs have a 60-day lock after registration or WHOIS changes.
