Czech Republic
Overview
CZ.NIC has invested unusually heavily in DNS security infrastructure, and the registry it runs for the Czech Republic reflects that engineering emphasis. Approximately 1.4 million domains sit under .cz, which was delegated in 1993. Registration is open to applicants anywhere with no local-presence condition. Czech businesses and a comparatively large domestic technology sector supply most of the demand, and the extension is the default choice for addressing the national market.
