Brazil's .com.br: 33.7 Million Domains, 147 Categories, and the Internet's Most Opinionated Namespace
We parsed 33.7 million domains in the .br namespace from our dataset: .com.br holds 97.3%, followed by .net.br at 1.3% and .org.br at 0.8%. Brazil built the most elaborate domain categorization system on Earth — 147 second-level categories, mandatory government ID for every registration, credential-verified professional domains for licensed dentists, lawyers, and engineers — and deliberately refused to simplify it. How a multi-stakeholder committee, a physics lab in Illinois, and a 37-year leader built the only major namespace still growing.
