Enter a domain or IP address to see its registration record.
How to look up a domain
- Type a domain such as example.com, or paste a full web address. An IP address works too.
- Press Look up. The tool asks the registry that manages the domain.
- Read the record: registrar, dates, status and name servers.
- Open the raw RDAP data if you need every field, for example to copy it into a report.
How to read the result
| Field | What it tells you |
|---|---|
| Registrar | The company the domain was registered through |
| Registered on / Expires on | When the domain was created and when it must be renewed |
| Status | Locks and states such as client transfer prohibited, which protects against unwanted transfers |
| Name servers | Where the domain DNS is hosted |
| DNSSEC | Whether the domain publishes signed DNS records |
Tips
- Check the expiry date before you buy a domain from someone, or to avoid letting your own lapse.
- Name servers often show which host or DNS provider a site uses.
- If you type a subdomain such as www.example.com, the tool shows the record of the main domain.
- Use the raw data view when you need exact timestamps and codes.
Limits to know about
- Owner names, emails and phone numbers are usually redacted by registrars for privacy. Do not expect to see them.
- Some country registries do not offer RDAP, or block browser requests. Those domains show a not-found or error message.
- Newly registered or just-updated domains may take a while to appear.
- This is not legal proof of ownership.
Privacy
The domain or IP you type is sent to rdap.org, a public bootstrap service that forwards the request to the right registry. ToolsRiver does not store your searches.
Frequently asked questions
What is the difference between WHOIS and RDAP?
Both publish domain registration data. RDAP is the newer standard with structured results, and it is now required for most generic domains like .com and .org.
Why can I not see the domain owner?
Privacy rules and registrar practice hide personal details by default. Registrar abuse contacts are usually still shown.
What does client transfer prohibited mean?
It is a lock set through the registrar that stops the domain from being transferred away without the owner unlocking it.
Why does a domain say not found?
It may not be registered, or its registry may not support RDAP yet. Check the spelling too.
Can I look up an IP address?
Yes. The tool shows the network name, address range, country and organisation for the block that contains the address.
About this tool
Built by the ToolsRiver team. Tested in Chrome on a desktop computer in November 2026 with .org, .co.uk, .in, an IP address, a subdomain, a missing domain, and invalid input. Some registries may behave differently.
