About WHOIS Lookup
Shows the public registration record for a domain: when it was registered, how old it is, when it expires, which registrar manages it, its status codes and its name servers. The data comes from RDAP, the JSON service that registries run in place of the older WHOIS text format, found through the IANA directory of RDAP servers. Status codes such as clientTransferProhibited are explained in plain English. If you enter a subdomain such as blog.example.com, the tool shows the record of the registered domain above it. Owner and contact details are not shown, because most registries redact them. Our server makes the request after human verification, so the domain you enter is sent to our server and to the registry; nothing is stored beyond a short in-memory cache.
When to use WHOIS Lookup
WHOIS Lookup FAQ
Is this the same as a WHOIS lookup?
It answers the same question using RDAP, which registries and registrars are required to offer in place of port-43 WHOIS. The fields are similar, but the data is structured, and owner contact details are usually redacted.
Does domain age mean how old the website is?
No. It is counted from the registration date the registry reports. A site can be older than a domain that moved to a new registration, and a domain that expired, was deleted and was registered again shows the newer date. Page history needs a web archive, not a registry.
Why is there no owner name or email?
Registries and registrars redact personal registrant data under privacy rules such as the GDPR, so the public record normally has none. This tool does not try to show it.
What does a status like clientTransferProhibited mean?
It is an EPP status code. This one is a registrar lock that stops the domain being transferred to another registrar, and it is normal on a domain in good standing. Codes starting with server are set by the registry. Others, such as redemptionPeriod and pendingDelete, show that a domain has expired and may soon be released.
Why does it say my domain extension is not supported?
The tool looks up each extension in the IANA RDAP directory. Some country-code extensions do not publish an RDAP service there, so there is nothing for it to ask. Their own registry website may offer a lookup.
Why did a subdomain return the main domain's record?
Only registered domains have records. For blog.example.com the tool asks about it, then about example.com, and tells you which record it found. It does not use a public-suffix list, so for names with many labels it stops after four tries.
Is there a limit?
Lookups are limited to 20 an hour for each connection, and results are cached for an hour. The data comes from the registry's live record, so a very recent change may take a short while to appear.
