Search a specific .cu name to check availability and use the technical page for documented eligibility rules. A seller’s standard price does not decide whether an applicant or a particular name qualifies.
Review the registry DNSSEC fields and the chosen registrar’s documented DNSSEC feature. The available data does not establish an individual-domain DNSSEC workflow for .cu.
The registry record currently does not establish every policy or syntax field for .cu. Missing evidence is shown as unknown rather than treated as permission, a restriction, or a DNSSEC capability.
