Brazil's .br: 50.3 Million Hostnames, a Profession-Gated Namespace, and the Internet's Most Opinionated ccTLD
We counted 50.3 million observed hostnames in the .br namespace — the 8th-largest TLD on Earth and the largest ccTLD in the Americas. Brazil built the most elaborate domain categorization system of any country: a heavily-structured second-level system with com.br for commerce alongside dozens of credential-gated professional zones for licensed lawyers, doctors, and engineers, mandatory government ID for every registration, and no public direct .br registration. A 9 June 2026 A-record crawl shows 60.6% of those hostnames still resolve — slightly above the whole-namespace average. Refreshed June 2026 with first-party resolution data.
