Varying restrictions based on which second-level name registration is within
Structure
Registrations are at third level beneath various categories and they were allowed at the second level for institutions of third level education until 2000; a wide variety of second-level categories exist, but .com.br is still much more popular than others
.br is the Internetcountry codetop-level domain (ccTLD) for Brazil. It was administered by the Brazilian Internet Steering Committee (Comitê Gestor da Internet no Brasil) until 2005 and now it's administered by Brazilian Network Information Center (Núcleo de Informação e Coordenação do Ponto br). A local contact is required for any registration. Registrations of domain names with Portuguese characters are also accepted. Except possible for universities, the second level domain is fixed and defines the category. For example, site.art.br is in the art (music, folklore, etc.) category, and othersite.org.br is in the Non-governmental organization category. Institutions of third level education were allowed to use the second level domain and .edu.br, although some use .com.br. There are also some other few exceptions that were allowed to use the second level domain until the end of 2000. As of February 2007, most domain registrations ignore categories and register in the .com.br domain, which has over 90% of all registered domains. The .jus.br domain has mandatory DNSSEC use.
