CERN
The .cern top-level domain is a brand-specific domain operated by the European Organization for Nuclear Research (CERN). Originally created to support CERN’s scientific infrastructure and internal communications, it is used primarily for official CERN websites, research projects, and institutional services related to high-energy physics.
Restricted to CERN and its authorized entities; not open for public registration.
The .cern extension is a brand top-level domain in the Domain Name System (DNS). It is managed by European Organization for Nuclear Research (CERN). .cern was introduced in 2014. There are currently 97 domains registered under this extension. DNSSEC adoption stands at 1.0%.
Registration pricing for .cern is not publicly listed. Brand TLDs are typically restricted to the owning organization.
The .cern TLD was delegated to the European Organization for Nuclear Research (CERN) on August 16, 2014, as part of ICANN’s New gTLD program. CERN applied to use the domain to strengthen its digital identity and streamline access to scientific resources. It was initially planned as a single-registrant domain, with only CERN eligible to register names. No public registration has ever been offered.
Brand TLDs like .cern are part of ICANN's New gTLD Program launched in 2012, which expanded the domain namespace beyond traditional TLDs.
The .cern TLD is commonly used for the following purposes:

DNSChkr maintains a comprehensive TLD directory covering all 1,900+ active top-level domains. The data on this page combines multiple authoritative sources to provide information not found in standard TLD listings.
Domain registration counts and density analysis are computed daily from TLD zone files, providing accurate registration statistics rather than estimates.
DNSSEC deployment percentages are measured by scanning actual DNS records across all registered domains in each TLD zone.
Registration, renewal, and transfer prices are checked hourly across multiple accredited registrars and compared automatically.
DNS provider distribution is calculated from nameserver records, showing which hosting providers serve the most domains in each TLD.
Use DNSChkr tools to inspect any .cern domain: run a full DNS health check, check DNS propagation, look up WHOIS records, or verify email authentication.
