DNS / RDAP Lookup Enter a domain or URL, we query RDAP for each lookup.

What is RDAP?

When you register a domain name (e.g. yourdomain.com), the registry keeps a technical record: who is the registrar, when the domain was created, when it expires, which DNS servers it uses, etc.

RDAP (Registration Data Access Protocol) is the modern standard to access this information. Concretely, when you run a lookup here, we send a request to an RDAP server (e.g. rdap.nic.fr for .fr) and display the response in a more understandable way.

The data comes directly from the official registries. It is not used to “hack” a site, but to understand who is behind a domain name and whether it is still active.
