Registry type, operator and root-zone date are from IANA’s root zone database, checked 7 Aug 2026. Registered counts are read from the zone file ICANN publishes through its Centralized Zone Data Service. A name absent from the zone has no nameservers, which strongly suggests it is unregistered, though a parked or expiring domain looks identical.
