Example result
What the WHOIS lookup shows you
You enter a domain, and the tool queries the responsible registry via RDAP or traditional WHOIS and shows the registrar, registration and expiration dates, status, and name servers. The registrar and dates below are fictional; your result depends on the domain.
Example · Example with fictional domain example.com
Input
- Domain
- example.com
- Omit www. and https://; the tool also removes both automatically.
Output
- Registrar
- Example Registrar, Inc.
- Created
- 14 April 2015
- Expires
- 14 April 2027
- The domain is registered until this date and must then be renewed.
- Last modified
- 2 March 2026
- Status
- client delete prohibited, client transfer prohibited, client update prohibited
- “client transfer prohibited” means the domain is locked to prevent an unwanted transfer to another registrar.
- Name server
- NS1.EXAMPLE.NET, NS2.EXAMPLE.NET
Why this tool
All registration details at a glance
What the free domain WHOIS lookup offers you.
RDAP or classic WHOIS
Automatically uses RDAP if the domain extension supports it, and queries classic WHOIS for selected extensions without RDAP.
Registrar & status
See which registrar a domain is registered with and its status.
Registration date
Shows when a domain was registered, and therefore its age, if the registry publishes the date.
Expiration date
Shows when a domain's registration expires, if the registry publishes the date.
Nameservers
Shows the nameservers registered for the domain with the registry.
Paste a full URL
Feel free to paste a full address: the tool removes the scheme, a leading www., path, query, and port before the lookup.
Domains with non-ASCII characters
The tool automatically converts internationalized domains to Punycode before the lookup.
Expand raw response
Below the result, you can expand the registry's original response as RDAP JSON or WHOIS text.
Share the result via a link
After the lookup, your input appears as ?domain= in the address bar, so you can share or bookmark the result.
How it works
How the WHOIS lookup works
Find a domain's registration details in just a few steps.
Step 1
Enter domain
Enter a domain in the input field, such as example.com. You can also paste a full URL; the tool automatically removes the scheme, www., path, and port.
Step 2
Look up WHOIS
Start the lookup. Depending on the domain extension, the tool automatically uses RDAP or traditional WHOIS.
Step 3
Read registration details
Check the results for the registrar, registration and expiration dates, last update, status, and nameservers, where published by the registry.
Step 4
View raw response
Expand the raw response if you want to see the registry's original response.
Step 5
Share result
After the lookup, the address bar contains your input as ?domain=. Copy the link to share the results or access them again later.
Good to know
How to read WHOIS results
What WHOIS lookup data means—and what it doesn't reveal.
Understanding domain statuses
The tool shows status values exactly as provided by the registry. For example, “client transfer prohibited” means the domain is locked against transfers to another registrar, while “client delete prohibited” prevents deletion. Such locks are standard for many domains and don't indicate a problem.
Owner details and GDPR
The structured result doesn't include registrant details. Most registries no longer publish the domain owner's name due to GDPR; the raw response often shows only “REDACTED” or a privacy service. The registrar, dates, status, and nameservers remain visible.
.de domains and unsupported extensions
For automated .de domain queries, DENIC returns only the connection status, and the tool displays a note about it. If an extension has neither RDAP nor a configured WHOIS server, the tool reports that it isn't supported yet.
Nameservers show where a domain's DNS records are managed. Check DNS records with DNS Lookup

FAQ
Domain WHOIS Lookup FAQ
Brief answers about WHOIS, RDAP, and domain registration data.
For a domain, the WHOIS lookup shows the registrar, registration date, expiration date, last update, status, and nameservers, where published by the registry. You can also expand the registry's original response. Example using the fictional domain example.com: registrar Example Registrar, Inc., created on 14 April 2015, expires on 14 April 2027, status client delete prohibited, client transfer prohibited, client update prohibited, nameservers NS1.EXAMPLE.NET, NS2.EXAMPLE.NET.
Yes. You don't need an account or to sign in. To prevent abuse, there is a lookup limit per IP address, and the form waits a few seconds between lookups.
Usually not through WHOIS. Due to GDPR and privacy services, most registries no longer publish the owner's contact details; often, they just show “REDACTED”. The structured results therefore contain no owner details, only the registrar, dates, status, and nameservers. If you want to contact the owner, check the website's legal notice or contact the listed registrar.
The registration date in the results shows when the domain was registered, and therefore its age. The expiration date shows how long it is registered for. Both dates appear if the registry publishes them. If your own domain is about to expire, renew it in time or transfer it to ZAP-Hosting.
WHOIS is the older, unstructured text protocol over port 43. RDAP is its successor and returns structured JSON over HTTPS. The tool uses RDAP when the domain extension supports it and queries traditional WHOIS for selected extensions without RDAP.
The registry returned no record for this domain. It may still be available, but you won't know for sure until you register it. If the tool instead says the domain extension is not yet supported, neither RDAP nor a configured WHOIS server is available for that extension.
For privacy reasons, DENIC (the .de registry) returns only the connection status for automated WHOIS lookups, not registrar or date details. This is a limitation imposed by DENIC, not a tool error. The tool displays a note about it in the results.
You can enter a full URL: the tool automatically removes the scheme, a leading www., the path, query, and port. It converts domains with accented characters to Punycode before looking them up. This tool isn't designed for IP addresses; use the IP Location Lookup for those. Go to IP Location Lookup
