The .ck extension is the Country Code Top-Level Domain (ccTLD) for the Cook Islands, a self-governing island nation in the South Pacific associated with New Zealand. The registry operator for .ck domains is Vodafone Cook Islands, and while registering the main .ck domain isn't generally possible, various second-level domains like .co.ck, .org.ck, and .edu.ck can be registered by businesses and organizations, sometimes requiring a local presence or specific documentation.
