What is .ck?
A little context on Cook Islands: the capital is Avarua, languages include English and Cook Islands Māori, the currency is the Cook Islands dollar (CKD) and the international dialing code is +682.
IANA lists Telecom Cook Islands Ltd. as the manager of .ck, with an address in Cook Islands. The registry's website is http://www.vodafone.co.ck. ccTLD managers set their own policies — who can register, which second-level names exist, pricing to registrars — so those rules differ from country to country.
Under the hood, the root zone points to 4 name servers for .ck, none of them with an IPv6 address. There is no DS record for .ck in the root zone, which means the TLD is not DNSSEC-signed at the top level.
