# Domain Availability

Check a domain against the authoritative RDAP server listed in the IANA bootstrap registry. RDAP can identify registered domains and can indicate that a domain is probably available when the registry returns not found. Registrar checkout availability, premium pricing, aftermarket inventory, reserved names, and registration restrictions require registrar or registry availability data.
