What is .cz TLD

.cz is the country‑code top‑level domain (ccTLD) for the Czech Republic. It anchors national digital identity while serving global audiences through commerce, media, and public services. Within the .cz namespace, we track registrants, hosting, and DNS health to understand how .cz domains and .cz websites operate at scale. Our current index records 1,196,221 active registrations, of which 1,121,471 resolve to live sites; usage spans 87 countries, illustrating international reach beyond domestic holders. These counts enable baselining market share, estimating web visibility, and prioritizing outreach or compliance workflows. We enrich this with registrar footprints, name server patterns, and lifecycle signals to separate parked from functional assets. Download .cz domain datasets from webatla to explore the zone in depth.

History and key features of .cz TLD

The .cz TLD emerged in the early internet era and has matured through stable policy and technical stewardship. As adoption expanded, emphasis shifted to resilient DNS infrastructure and accurate registrant data, ensuring that .cz domains and .cz websites remain discoverable and measurable across networks. In our telemetry, 1,121,471 names publish DNS records, indicating active configuration, while fresh activity continues: 1,885 in December 2025 and 754 highlight recent registrations entering the zone. Tracking these cohorts illuminates renewal behavior, hoster consolidation, and risk exposure across IP ranges. Such longitudinal signals help benchmark growth against neighboring ccTLDs and identify emerging content categories within .cz websites. Download time-series .cz domain datasets from webatla for your analyses.

Why and who choose the .cz domain

Organizations choose the .cz domain to localize services for Czech users, comply with regional norms, and signal relevance in search and trust frameworks. Typical adopters include retailers, fintechs, SaaS providers, universities, and public bodies, though we observe global brands maintaining defensive .cz domains for brand control. Operationally, .cz websites reflect diverse hosting geographies and CDNs, supporting fast delivery to Central Europe and beyond. Scale matters when planning: we monitor 1,121,471 live .cz websites across 87 countries, enabling segmentation by sector, technology, and DNS operator. These insights support market entry, competitor mapping, and vulnerability surface assessment before acquisition or campaign spend. Download sector-filtered .cz domain datasets from webatla to benchmark adoption.
