De acordo com os desenvolvedores do projeto, o PowerDNS Authoritative Server gerencia aproximadamente 30% do total de dom\u00ednios na Europa (se considerarmos apenas dom\u00ednios com assinaturas DNSSEC, esse n\u00famero vai para 90%). O c\u00f3digo do projeto \u00e9 distribu\u00eddo sob a licen\u00e7a GPLv2.    <\/p>\n<p>O PowerDNS Authoritative Server oferece a possibilidade de armazenar informa\u00e7\u00f5es sobre dom\u00ednios em diversos bancos de dados, incluindo MySQL, PostgreSQL, SQLite3, Oracle e Microsoft SQL Server, al\u00e9m de LDAP e arquivos de texto simples no formato BIND. A resposta pode ser adicionalmente filtrada (por exemplo, para eliminar spam) ou redirecionada por meio da conex\u00e3o de manipuladores personalizados nas linguagens Lua, Java, Perl, Python, Ruby, C e C++. Dentre as caracter\u00edsticas, destaca-se ainda a coleta remota de estat\u00edsticas, incluindo por SNMP ou atrav\u00e9s da Web API (para estat\u00edsticas e gerenciamento, um servidor http embutido), rein\u00edcio instant\u00e2neo, um mecanismo interno para conex\u00e3o de manipuladores na linguagem Lua, e a possibilidade de balanceamento de carga considerando a localiza\u00e7\u00e3o geogr\u00e1fica do cliente.      <\/p>\n<p>Principais novidades:  <\/p>\n<ul>\n<li class=\"l\"> Foi adicionada a suporte para o cat\u00e1logo de zonas (&#171;Catalog Zones&#187;), facilitando a manuten\u00e7\u00e3o de servidores DNS secund\u00e1rios ao permitir que, em vez de definir em cada secund\u00e1rio <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/pt\/server\/dts-newyork\/\"   title=\"servidor\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"2727\">servidor<\/a> realiza-se a transfer\u00eancia do cat\u00e1logo de zonas secund\u00e1rias entre os servidores prim\u00e1rio e secund\u00e1rio. Ap\u00f3s a configura\u00e7\u00e3o da transfer\u00eancia do cat\u00e1logo, semelhante \u00e0 transfer\u00eancia de zonas individuais, as zonas criadas no servidor prim\u00e1rio marcadas como pertencentes ao cat\u00e1logo ser\u00e3o automaticamente criadas no servidor secund\u00e1rio sem necessidade de modificar arquivos de configura\u00e7\u00e3o. O cat\u00e1logo \u00e9 compat\u00edvel com backends de armazenamento gmysql, gpgsql, gsqlite3, godbc e lmdb.\n<li class=\"l\"> Durante a implementa\u00e7\u00e3o do cat\u00e1logo de zonas, foi realizada a otimiza\u00e7\u00e3o do c\u00f3digo para trabalhar com um grande n\u00famero de dom\u00ednios. Ao armazenar zonas em um SGBD, o n\u00famero de consultas SQL foi significativamente reduzido \u2014 agora, em vez de uma consulta separada para cada dom\u00ednio, \u00e9 feita uma sele\u00e7\u00e3o em grupo. Essa altera\u00e7\u00e3o teve um impacto positivo na performance. <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/pt\/server\/\"   title=\"servidores\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"1666\">servidores<\/a>, atendendo a um grande n\u00famero de zonas, mesmo em sistemas que n\u00e3o utilizam o cat\u00e1logo de zonas.\n<li class=\"l\"> Apoio ao mecanismo de troca de chaves GSS-TSIG foi reimplementado e retornado, que anteriormente foi removido devido a vulnerabilidades e potenciais problemas de seguran\u00e7a.\n<li class=\"l\"> Ao consultar registros Lua via TCP, foi assegurada a reutiliza\u00e7\u00e3o do estado Lua, o que aumentou significativamente a performance.\n<li class=\"l\"> No banco de dados baseado em lmdbbackend, foi implementado o v\u00ednculo ao UUID e a possibilidade de gera\u00e7\u00e3o de identificadores aleat\u00f3rios para objetos.\n<li class=\"l\"> Foi adicionado em pdnsutil e na API HTTP ferramentas para gerenciar servidores autoprimary, utilizados para automatizar a implanta\u00e7\u00e3o e atualiza\u00e7\u00e3o de zonas em servidores DNS secund\u00e1rios sem a necessidade de configura\u00e7\u00e3o manual das zonas secund\u00e1rias.\n<li class=\"l\"> Nova fun\u00e7\u00e3o Lua ifurlextup foi adicionada.\n<li class=\"l\"> Foi adicionado um processo em segundo plano experimental para gera\u00e7\u00e3o e entrega de chaves (key roller).        <\/ul>\n<p>Fonte: <a content=\"nofollow\" rel=\"nofollow\" href=\"https:\/\/www.opennet.ru\/opennews\/art.shtml?num=57958\">opennet.ru<\/a> <\/p>","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"excerpt":{"rendered":"<p>\u041e\u043f\u0443\u0431\u043b\u0438\u043a\u043e\u0432\u0430\u043d \u0440\u0435\u043b\u0438\u0437 \u0430\u0432\u0442\u043e\u0440\u0438\u0442\u0435\u0442\u043d\u043e\u0433\u043e (authoritative) DNS-\u0441\u0435\u0440\u0432\u0435\u0440\u0430 PowerDNS Authoritative Server 4.7, \u043f\u0440\u0435\u0434\u043d\u0430\u0437\u043d\u0430\u0447\u0435\u043d\u043d\u043e\u0433\u043e \u0434\u043b\u044f \u043e\u0440\u0433\u0430\u043d\u0438\u0437\u0430\u0446\u0438\u0438 \u043e\u0442\u0434\u0430\u0447\u0438 DNS-\u0437\u043e\u043d. \u041f\u043e \u0434\u0430\u043d\u043d\u044b\u043c \u0440\u0430\u0437\u0440\u0430\u0431\u043e\u0442\u0447\u0438\u043a\u043e\u0432 \u043f\u0440\u043e\u0435\u043a\u0442\u0430, PowerDNS Authoritative Server \u043e\u0431\u0441\u043b\u0443\u0436\u0438\u0432\u0430\u0435\u0442 \u043f\u0440\u0438\u043c\u0435\u0440\u043d\u043e 30% \u0438\u0437 \u043e\u0431\u0449\u0435\u0433\u043e \u0447\u0438\u0441\u043b\u0430 \u0434\u043e\u043c\u0435\u043d\u043e\u0432 \u0432 \u0415\u0432\u0440\u043e\u043f\u0435 (\u0435\u0441\u043b\u0438 \u0440\u0430\u0441\u0441\u043c\u0430\u0442\u0440\u0438\u0432\u0430\u0442\u044c \u0442\u043e\u043b\u044c\u043a\u043e \u0434\u043e\u043c\u0435\u043d\u044b \u0441 \u043f\u043e\u0434\u043f\u0438\u0441\u044f\u043c\u0438 DNSSEC, \u0442\u043e 90%). \u041a\u043e\u0434 \u043f\u0440\u043e\u0435\u043a\u0442\u0430 \u0440\u0430\u0441\u043f\u0440\u043e\u0441\u0442\u0440\u0430\u043d\u044f\u0435\u0442\u0441\u044f \u043f\u043e\u0434 \u043b\u0438\u0446\u0435\u043d\u0437\u0438\u0435\u0439 GPLv2.
