.cu domain extension

The .cu domain is the country code for Cuba, managed by CENIAInternet in Havana. It is a restricted ccTLD, with registration limited to entities and individuals who have a legitimate presence in Cuba. The domain has been active since June 1992, giving it one of the longer histories among Caribbean ccTLDs. Registration services are handled through nic.cu. As with most country code domains, .cu is primarily used by Cuban businesses, organizations, and residents, though international interest exists due to its brevity and association with the chemical element copper. The sponsor, CENIAInternet, maintains the registry from its offices at the Capitolio Nacional in Havana.
