How it works
RDAP 404 means no registration record was found. A DNS record proves a domain is in use but absent DNS never proves availability. Confirm premium pricing with a registrar.
- Paste one full domain per line, up to 20.
- Review available, registered and unknown results.
- Confirm availability and price at your registrar.
