Domain Tools shows the public registration details of a domain name. The data is read from RDAP, the modern replacement for WHOIS, which registries use to publish information about registered domains.
You can see when a domain was registered, when it expires, which registrar manages it and which name servers it uses.
The result is grouped into registration details, status and name servers.
| Field | Meaning |
|---|---|
| Registered on | The date the domain was first registered. |
| Expires on | The date the registration ends, with the number of days left. |
| Last changed | The date the registration record was last updated. |
| Registrar | The company that manages the registration. |
| Status | Codes such as client transfer prohibited, which locks a domain against unwanted transfers. |
| Name servers | The servers that host the DNS records of the domain. |
| DNSSEC | Digital signatures that protect DNS answers from tampering. |

Quick answers about Domain Tools.
Registries and registrars hide personal contact details by default to protect privacy. The registrar, dates and status are still shown.
RDAP is the Registration Data Access Protocol. It replaces WHOIS and returns structured, standardized data.
The domain may not be registered. This alone does not prove it can be bought, so check with a registrar.
Some extensions, especially some country-code ones, do not provide RDAP, so no data can be shown for them.
