What is a WHOIS Lookup?
WHOIS lookups allow you to view the details behind a given domain. Every domain that exists has a record indicating who registered it, when it was registered, who the registrar is, when it will expire, etc. A WHOIS Lookup allows you to access that record.
There are many possible use cases for WHOIS lookups. You may want to check a domain's history because you are interested in buying it. You may want to check the owner of an email address after you received a suspicious email. You may want to look up the owner of a domain that you visit. In any of these cases, a WHOIS lookup is the appropriate tool.
Our WHOIS lookup tool communicates with the RDAP servers (the newer, better version of the classic WHOIS service). Unlike other tools, we do not store or provide any cached or invented information. Just enter a domain and submit the request to access two tables with real WHOIS data.
What can you expect to see?
After a WHOIS Lookup, our tool will provide you two tables. The first will show you the registry handle, the status flags, the name servers, the creation and expiration dates, and the registrars. This provides vital information about a domain.
How to Use the WHOIS Lookup
The WHOIS look-up tool is extremely easy to use. In fact, it can be accomplished in only a few steps.
- Enter the domain name (example: example.com).
- Excluding “http://” or “https://” in the entry is preferred.
- Hit the Lookup WHOIS button.
The results will be displayed. The first of the tables will include the data on the domain registration, while the subsequent table will include the registrar and the contact for abuse.
Tips for Precise WHOIS Lookups
- Make sure to use the root domain. For the most complete record, enter “example.com” instead of “www.example.com.”
- Try RDAP first. The newer RDAP protocol, which is a structured replacement of the outdated WHOIS service, is preferred by our tool.
- Check the status flags. Should the status of the domain be clientTransferProhibited, this means that the domain has been locked against transfer requests.
- The abuse contact should only be used to report malicious activity. This will not be answered if it is concerning a non-malignant foreign inquiry.
Privacy Note
We forward your query to the registry and return the response directly. We do not store the domain you looked up, the results, or your IP address. The WHOIS lookup is completely private and free to use, with no account required.
Frequently Asked Questions
What is WHOIS?
WHOIS is a public directory protocol that returns the registration details of a domain name, including the owner, registrar, dates, and name servers. A WHOIS lookup is a query against this directory.
Is the WHOIS lookup tool free?
Yes. Our WHOIS lookup tool is 100% free, with no sign-up, no rate limits, and no captchas.
What protocol does the tool use?
Our tool uses RDAP (Registration Data Access Protocol), the modern, structured successor to the legacy WHOIS protocol. RDAP returns standardized JSON responses, which means faster and more accurate results.
Why is some information hidden?
Some domain owners use a privacy or proxy service offered by their registrar. In that case, the registrar's contact details appear in the WHOIS lookup instead of the owner's personal information.
Can I look up any TLD?
Our WHOIS lookup supports any gTLD or ccTLD that publishes RDAP data, which includes the vast majority of registered domains on the internet.
