Pense nisso como um apelido: em vez de dizer \u201cesse nome est\u00e1 associado a este IP\u201d, um CNAME indica que \u201cesse nome \u00e9, na verdade, apenas outro nome para aquele\u201d. Os registros CNAME s\u00e3o extremamente comuns ao conectar servi\u00e7os de terceiros ao seu dom\u00ednio.<\/p>\n<h2>Como um registro CNAME difere de um registro A<\/h2>\n<p>A principal diferen\u00e7a est\u00e1 no que cada registro aponta. Um registro A mapeia um nome diretamente para um endere\u00e7o IP num\u00e9rico, enquanto um CNAME mapeia um nome para outro nome de host, que \u00e9 ent\u00e3o resolvido para um endere\u00e7o IP. Isso \u00e9 importante porque, se o endere\u00e7o IP do destino mudar, um CNAME continua funcionando automaticamente, ao passo que um registro A precisaria ser atualizado. Resumindo:<\/p>\n<ul>\n<li><strong>Um recorde:<\/strong> nome para endere\u00e7o IP (por exemplo, yourdomain.com para 192.0.2.10).<\/li>\n<li><strong>CNAME:<\/strong> nome para outro nome (por exemplo, www.yourdomain.com para yourdomain.com).<\/li>\n<\/ul>\n<h2>Usos comuns dos registros CNAME<\/h2>\n<ul>\n<li><strong>A vers\u00e3o www:<\/strong> direcionar www.yourdomain.com para o seu dom\u00ednio raiz.<\/li>\n<li><strong>Ferramentas de terceiros:<\/strong> servi\u00e7os de integra\u00e7\u00e3o, como plataformas de marketing por e-mail, centrais de atendimento ou criadores de sites, que solicitam que voc\u00ea adicione um CNAME.<\/li>\n<li><strong>Verifica\u00e7\u00e3o:<\/strong> Alguns provedores utilizam um CNAME para confirmar que voc\u00ea \u00e9 o propriet\u00e1rio do dom\u00ednio.<\/li>\n<li><strong>Subdom\u00ednios para servi\u00e7os externos:<\/strong> redirecionar shop.yourdomain.com para uma plataforma de loja virtual hospedada.<\/li>\n<\/ul>\n<h2>Como adicionar um registro CNAME<\/h2>\n<ul>\n<li>Fa\u00e7a login no seu gerenciador de DNS ou no seu painel de controle.<\/li>\n<li>Abra o <strong>DNS<\/strong> ou <strong>Editor de zonas<\/strong> se\u00e7\u00e3o.<\/li>\n<li>Criar um novo <strong>CNAME<\/strong> registro.<\/li>\n<li>Digite o nome do subdom\u00ednio no campo \u201chost\u201d (por exemplo, <em>www<\/em> ou <em>loja<\/em>).<\/li>\n<li>Digite o nome do host de destino no campo de valor, exatamente como fornecido pelo servi\u00e7o.<\/li>\n<li>Salve e aguarde o tempo necess\u00e1rio para a propaga\u00e7\u00e3o.<\/li>\n<\/ul>\n<h2>Regras importantes a serem lembradas<\/h2>\n<p>H\u00e1 algumas restri\u00e7\u00f5es que vale a pena conhecer. Um CNAME n\u00e3o pode ser usado no dom\u00ednio raiz (simplesmente \u201cseudominio.com\u201d) no DNS padr\u00e3o; portanto, o dom\u00ednio raiz normalmente usa um registro A, enquanto \u201cwww\u201d usa um CNAME. Al\u00e9m disso, um nome de host que possua um CNAME n\u00e3o deve ter outros registros com o mesmo nome, pois isso causa conflitos.<\/p>\n<h2>Solu\u00e7\u00e3o de problemas<\/h2>\n<ul>\n<li><strong>O servi\u00e7o n\u00e3o est\u00e1 verificando:<\/strong> confirme se o valor de destino corresponde exatamente, sem erros de digita\u00e7\u00e3o no final.<\/li>\n<li><strong>Erros de conflito:<\/strong> remova todos os registros duplicados referentes ao mesmo host.<\/li>\n<li><strong>Ainda n\u00e3o resolvido:<\/strong> aguarde o tempo necess\u00e1rio para a propaga\u00e7\u00e3o e verifique novamente por meio de uma consulta de DNS.<\/li>\n<\/ul>\n<h2>Precisa de ajuda?<\/h2>\n<p>Se um servi\u00e7o de terceiros estiver solicitando um CNAME e voc\u00ea n\u00e3o souber onde inseri-lo, nossa equipe de suporte poder\u00e1 adicion\u00e1-lo corretamente para voc\u00ea por meio do chat ao vivo.<\/p>","protected":false},"excerpt":{"rendered":"<p>A CNAME record (Canonical Name record) is a type of DNS entry that points one domain name to another domain name, rather than to an IP address.
