Em seu auge, o PowerDNS Authoritative Server serviu at\u00e9 30% de todos os dom\u00ednios na Europa e at\u00e9 90% dos dom\u00ednios com DNSSEC. O c\u00f3digo do projeto \u00e9 distribu\u00eddo sob a licen\u00e7a GPLv2.    <\/p>\n<p>O PowerDNS Authoritative Server permite armazenar informa\u00e7\u00f5es sobre dom\u00ednios em v\u00e1rias bases de dados, incluindo MySQL, PostgreSQL, SQLite3, LMDB, Oracle e Microsoft SQL Server, assim como em LDAP e arquivos de texto simples no formato BIND. As respostas podem ser filtradas adicionalmente (por exemplo, para bloqueio de spam) ou redirecionadas para manipuladores pr\u00f3prios nas linguagens Lua, Java, Perl, Python, Ruby, C e C++.
