A WHOIS lookup shows the public registration data of a domain name: who owns it, when it was registered and when it expires.
Every domain name is registered through a registrar and stored in the WHOIS database managed by ICANN. A WHOIS lookup reads this database and returns the domain information: the registrant, the registrar, the creation date and the expiration date. It works for most domain extensions, and modern tools use the RDAP protocol to fetch the same data.
The results of a WHOIS search include contact information such as the registrant name and organization, the technical contact, the name servers, and the domain status codes. Some owners use WHOIS privacy to hide personal contacts, so the response shows the privacy service instead. Even then, you still see the registrar and the registration data.
You can use the WHOIS lookup tool to check a domain before you buy it, verify who owns a domain you want to acquire, or review your own domains before renewal. It is the fastest way to get domain information about any name — and the same data your registrar sees.
A WHOIS lookup shows the expiration date today. Monitoring keeps watching your domains and notifies you before renewal, so a domain name never drops by accident. No credit card required.
Get the full registration data for any domain name in three simple steps.
Type the domain name you want to check, for example example.com, and click the Lookup button. You can also paste a full URL — the tool extracts the domain automatically.
Read the WHOIS results: registrant and contact information, registrar, creation and expiration dates, name servers, and domain status. If WHOIS privacy is enabled, you will see the privacy service instead of personal details.
Check if the domain is available to register, find out who owns a domain you want to buy, or plan the renewal before the expiration date. Export or copy the details and keep them with your domain records.
These are the most common problems people find when they run a WHOIS lookup on a domain.
The WHOIS lookup shows an expiration date that is close or already in the past.
Renew the domain as soon as possible through your registrar, and enable auto-renewal so the domain name is never lost.
The registrant contact shows a privacy service instead of a real person or company. This is normal — the owner uses WHOIS privacy.
You can still see the registrar and contact them through the form on the registrar page.
The email or phone in the registration data is outdated, and you are not receiving renewal notices.
Log in to your registrar account and update the contact information, because the registrar sends important notices to that address.
The WHOIS result shows status codes such as clientTransferProhibited, which means the domain is locked.
If you want to transfer the domain, unlock it in the registrar panel and request an authorization code.
Get notified before the expiration date so your domain name is always renewed on time.
See changes in the WHOIS database: new registrant, new registrar, updated dates and status codes.
Receive an alert if someone changes the contact information or unlocks your domain without permission.
Monitor the registration data of all your domain names from one dashboard, in any extension.
Stop running WHOIS lookups by hand. The monitoring checks the WHOIS database for you around the clock.
Begin with a free plan and monitor your first domains without paying anything.
A WHOIS lookup shows the expiration date today. Monitoring keeps watching your domains and notifies you before renewal, so a domain name never drops by accident. No credit card required.
Small habits that keep your domain registration data safe.
Run a WHOIS lookup on your domains once a month and note the expiration date. Renew early and enable auto-renewal.
Registrars send renewal and transfer notices to the email in the WHOIS database. Update the contact information after any change of email or phone.
WHOIS privacy hides personal data in the database, but your registrar still knows the real contacts. Keep the account email valid.
Use the WHOIS lookup before registering a name to see if it is available, and check the history of an expired domain you plan to buy.
A manual WHOIS search shows one moment in time. Use monitoring to see how the registration data changes over weeks and months.
A WHOIS lookup is a query that reads the public registration data of a domain name from the WHOIS database. The response shows who owns the domain, the registrar, the creation and expiration dates, and the name servers.
Enter a domain name in the lookup field and press the button. The tool queries the WHOIS database, collects the registration data, and shows the results with the registrant, registrar and dates.
A standard result includes the registrant and contact information, the registrar, the creation date, the expiration date, the name servers, and the domain status codes.
Run a WHOIS lookup on the domain name. The response shows the registrant name and organization. If WHOIS privacy is enabled, contact the registrar to reach the owner.
Yes. The WHOIS lookup is free and unlimited — you can check any domain name at any time. Monitoring plans add alerts and continuous checks if you need them.
The expiration date is the day when the domain registration ends unless it is renewed. Check it with a WHOIS lookup and renew the domain name before that date to keep it.
The owner uses WHOIS privacy, a service that replaces personal data in the database with the privacy provider’s details. Your registrar still has the real contact information. Check the registrar’s privacy policy for details.
RDAP is the modern protocol that replaced the old WHOIS protocol for getting registration data. It returns the same domain information in a structured format and is used by ICANN and most registries.
Status codes describe the state of a domain: active, pending renewal, locked for transfer, and similar. A WHOIS lookup shows them, and they help you understand why a domain cannot be transferred.
Perform a WHOIS lookup for the domain name. The domain registrar is listed in the registration data, and the response usually includes the registrar’s website and abuse contact.
Yes, you can check most top-level domains. If a domain is available, you can register domain names with the same registrar, and the amount of WHOIS information may differ by extension.
Check before buying a domain and before renewal of your own names. For regular control, use monitoring so you get an alert when the registration data changes or the expiration date approaches.
