DNS and Domain ToolsDomain lookup (RDAP, the modern WHOIS)
Type a domain name to see its registry record: registrar, dates, name servers and status.
What it does
The tool asks the registry of the domain's top-level domain (.com, .in, .dev and so on) for its record, using RDAP, the successor of WHOIS. It finds the right registry from the list that IANA publishes (the RDAP bootstrap file, publication date shown on the page). You see the registrar, the registration and expiry dates, the name servers, whether DNSSEC is on, and the status codes with a plain explanation.
What you will not see
Registries hide the personal details of owners. Many do not offer RDAP at all (the tool says so). Subdomains are not registered separately, so a lookup for www.example.com finds nothing: look up example.com.
How it was tested
We read the same records with a script and compared registration date, expiry date, name servers and status for .com, .net, .org, .in, .dev and .co.uk names: all matched the tool's reading.
Use it for
- Checking when your own domain expires.
- Seeing which name servers a domain really uses.
- Looking for a lock such as
client transfer prohibitedbefore you move a domain.
Is the expiry date exact?
It is what the registry reports. Registrars may give a grace period after it. Renew before the date.
Where does my query go?
