What is .ck TLD

.ck is the country-code top-level domain (ccTLD) designated for the Cook Islands. We define this namespace as a compact, lightly trafficked zone where registration is typically mediated through designated second-level labels. In the global context, .ck domains appear across multiple networks and hosting locations, and .ck websites tend to be sparse and specialized compared with larger ccTLDs. From our index, 421 active records are visible, with 421 live sites and usage spanning 17 countries. This scale means .ck domains provide focused signals for researchers, threat analysts, and brand stewards surveying smaller registries. We monitor resolution, availability, and lifecycle events to keep .ck websites measurable over time. Download webatla’s .ck domain datasets to deepen your analysis.

History and key features of .ck TLD

Established as the Cook Islands’ ccTLD, .ck has historically been organized under structured second-level categories (for example commerce and organizations), with relatively conservative growth patterns compared with broader TLDs. We observe that policy constraints and limited registrant demand have shaped the footprint of .ck domains and the cadence of .ck websites coming online. Over the latest period, we detected 0 new registrations and 1 in February 2026, while 421 domains currently publish DNS records, indicating an active resolution baseline. These features make .ck useful as a controlled case for studying registration churn, DNS hygiene, and hosting shifts. Our longitudinal crawling normalizes nameserver, MX, and web stack attributes so .ck websites can be compared with peer ccTLDs. Download the historical .ck domain dataset from webatla.

Why and who choose the .ck domain

Organizations with ties to the Cook Islands, regional initiatives, researchers, and brand-protection teams typically consider .ck domains when local relevance, limited namespace contention, or defensive coverage is required. Because .ck websites are few relative to population, the signal-to-noise ratio can benefit threat intelligence, takedown monitoring, and portfolio management. Our telemetry shows a compact ecosystem: 421 active names, 421 live .ck websites, and usage seen across 17 countries. This distribution supports cross-jurisdiction analysis of hosting, SSL adoption, and mail exposure among .ck domains, informing risk and investment decisions. We provide normalized, export-ready datasets to integrate with SIEM, marketing, or research pipelines. Download the full .ck domain dataset from webatla today.
