Online Whois Lookup Tool
Query domain registration details, registrar information, creation and expiration dates, and assigned name servers via official RDAP protocols.
Free Online Whois Lookup Tool
A Whois lookup shows the public registration record of a domain name. With it, you can find out which registrar holds the domain, when it was first registered, when it expires, and which name servers it uses. This tool queries RDAP, the modern replacement for the classic Whois protocol, and shows the results in seconds. People use it to check whether a domain is about to expire, to estimate a domain’s age, and to look into suspicious websites.
How to Use the Whois Lookup
- First, enter a domain name. Type the domain only, such as example.com, or click one of the example domains under the box.
- Next, press Lookup Whois. The tool contacts the public RDAP servers for that domain.
- Then, read the summary. The four cards show the domain, the registrar, the creation date and the expiration date.
- After that, scroll to the full record. The Whois / RDAP Record Output section lists everything the registry published.
- Finally, press Clear to start a new search.
What the Results Mean
| Result | What it tells you |
|---|---|
| Queried Domain | The domain name you searched for. |
| Registrar | The company where the domain is registered. This is a sales company, not necessarily the owner. |
| Creation Date | When the domain was first registered, which gives you its age. |
| Expiration Date | When the registration ends unless the owner renews it. |
| Full record | The complete RDAP data, which usually includes name servers, status codes and often redacted contact details. |
Common Domain Status Values
The full record lists one or more status values. The wording differs slightly between registries, but these are the most common:
| Status | Meaning |
|---|---|
| active | The domain is registered and working normally. |
| client transfer prohibited | The registrar has locked the domain against transfers. This is a normal protective setting. |
| client delete prohibited, client update prohibited | Locks that prevent accidental deletion or changes. |
| redemption period | The domain expired, and the owner can still recover it, usually for an extra fee. |
| pending delete | The domain will soon be released for new registrations. |
Whois vs RDAP
Whois is the older text-based system for looking up domain registrations. RDAP, the Registration Data Access Protocol, is its modern replacement. It returns structured data over HTTPS, supports better privacy controls, and is now the standard that ICANN pushes registries and registrars toward. Because of this, the results of a lookup are usually called a Whois record even when they come from RDAP.
Why Owner Details Are Often Hidden
Many records show “redacted for privacy” instead of a name, address or email. Privacy regulations such as the GDPR and registrar privacy services hide personal details by default. As a result, a missing owner name is normal and says nothing about whether a website is trustworthy. If you need to contact the owner, most registrars offer a contact form or an abuse contact address.
How to Check When a Domain Expires
- Enter the domain and press Lookup Whois.
- Read the Expiration Date card.
- If the date has passed, the domain may still be in a grace period, during which the owner can usually renew at a normal price. After that, a redemption period often applies, with extra fees. These rules vary by registry and registrar.
If you own the domain, renew it well before the date, because an expired domain can stop your website and your email.
How to Check the Age of a Domain
- Use the Creation Date. Subtract it from today’s date to get the domain’s age.
- Transfers do not reset the age. Moving a domain to a new registrar keeps the original creation date.
- Do not rely on age alone. An old domain is not automatically trustworthy, and a new domain is not automatically bad.
Using Whois for Basic Security Checks
Whois data is a useful first clue when a link looks suspicious, as long as you treat it as a clue and not as proof:
- Check the creation date. A domain that imitates a well-known brand but was registered only days ago deserves extra caution.
- Look at the registrar and name servers. If they look nothing like the real company’s setup, compare them with the genuine domain.
- Do not treat hidden details as suspicious. Most legitimate domains use privacy protection now.
- Combine several checks. Look at the DNS Lookup and the IP Lookup as well.
- Report real phishing. Send it to the registrar’s abuse contact and to the impersonated company.
What a Whois Lookup Cannot Tell You
- Who really owns a domain when privacy protection is on.
- Whether a website is safe. Registration data says nothing about the site’s content.
- Where the site is hosted. For that, use the IP Lookup.
- How popular or reputable the site is.
Tips for Better Results
- Enter only the domain name. If you copy a full web address, remove the https:// and everything after the domain.
- Use the main domain, not a subdomain. Records exist for registered domains, so blog.example.com has no record of its own. Search example.com instead.
- Check your spelling. A small typo returns no record.
- Wait a moment and retry if a search fails, because public RDAP servers sometimes limit how often they answer.
What to Expect and Limits
- Not every domain ending supports RDAP. Most generic endings such as .com, .net and .org do, but some country-code domains do not yet, so those searches may return no record.
- No record does not prove a domain is free. Confirm availability with a registrar before you rely on it.
- Changes can take time to appear. A renewal or transfer may not show in the record immediately.
- The tool shows what registries publish. It cannot reveal information that is redacted or hidden.
Privacy and Responsible Use
The lookup runs from your browser, which sends the domain name to public RDAP servers to get the record. That is how any Whois lookup works. Please use the results responsibly: registration data is public, but you should not use it to spam, harass or stalk anyone.
Frequently Asked Questions
1. Is this Whois lookup free?
Yes. It is free, needs no account and has no search limit on our side. However, public RDAP servers may slow down very rapid repeat searches.
2. What is the difference between Whois and RDAP?
Whois is the older text-based lookup system. RDAP is its modern replacement, which returns structured data over HTTPS and handles privacy better. This tool uses RDAP.
3. Why can I not see the owner’s name or email?
Privacy regulations and registrar privacy services hide personal details in most records. This is normal, and it does not mean the domain is suspicious.
4. How do I check when a domain expires?
Enter the domain and read the Expiration Date card. The full record below it may also show status values such as redemption period if the domain has already expired.
5. How do I find out how old a domain is?
Look at the Creation Date. A transfer to a new registrar does not change it, so it shows when the domain was first registered.
6. Can I use this tool to check if a domain is available?
It can give a hint, because an unregistered domain usually returns no record. However, confirm availability with a domain registrar before you rely on it.
7. Does the tool work for every domain ending?
It works for domains whose registries support RDAP, which includes most common endings such as .com, .net and .org. Some country-code domains do not support it yet, so those searches may return no record.
8. Is it legal to look up a domain?
Yes. Registration data is public information. Just use it responsibly, and never for spam, harassment or stalking.
