\"Como<\/a><\/noindex><\/p>\n

Para esconder o endere\u00e7o IP ou contornar bloqueios de conte\u00fado, normalmente s\u00e3o utilizados proxies. Eles v\u00eam em diferentes tipos. Hoje, vamos comparar dois dos tipos mais populares de proxies \u2013 os proxies de servidor e os residenciais, discutir suas vantagens, desvantagens e cen\u00e1rios de uso.<\/a><\/noindex><\/p>\n

Como funcionam os proxies de servidor<\/h2>\n

\nOs proxies de servidor (Datacenter) s\u00e3o o tipo mais comum. Ao utiliz\u00e1-los endere\u00e7os IP<\/a> eles s\u00e3o fornecidos por provedores de servi\u00e7os em nuvem. Esses endere\u00e7os n\u00e3o est\u00e3o relacionados aos provedores de internet de banda larga. <\/p>\n

Os proxies de servidor s\u00e3o usados para esconder o verdadeiro endere\u00e7o IP ou contornar bloqueios de conte\u00fado com base em dados geogr\u00e1ficos, al\u00e9m de criptografar o tr\u00e1fego. Muitas vezes, certos servi\u00e7os web limitam o acesso a usu\u00e1rios de determinados pa\u00edses \u2013 como o Netflix. Usu\u00e1rios dessas localidades podem, por meio de proxies de servidor, obter um endere\u00e7o IP nos EUA e contornar a restri\u00e7\u00e3o. <\/p>\n

Vantagens e desvantagens dos proxies de servidor<\/h2>\n

\nOs proxies de servidor s\u00e3o f\u00e1ceis de usar e conseguem realizar sua fun\u00e7\u00e3o principal \u2013 ocultar o verdadeiro endere\u00e7o IP e abrir acesso a conte\u00fados bloqueados.<\/p>\n

\u00c9 importante entender que, no caso dos proxies de servidor, os endere\u00e7os IP n\u00e3o s\u00e3o fornecidos pelo provedor de internet residencial, mas sim por provedores de hospedagem. Muitos recursos web modernos limitam as conex\u00f5es de endere\u00e7os IP de servidores, uma vez que s\u00e3o frequentemente utilizados por diversos bots.<\/p>\n

Como funcionam os proxies residenciais<\/h2>\n

\nPor outro lado, um proxy residencial \u00e9 um endere\u00e7o IP fornecido por um provedor de internet real de uma determinada cidade, regi\u00e3o ou estado. Normalmente, esses endere\u00e7os s\u00e3o fornecidos a propriet\u00e1rios de im\u00f3veis, e s\u00e3o registrados em bancos de dados de registradores regionais de internet (RIR). Quando utilizados corretamente, as solicita\u00e7\u00f5es a partir desses endere\u00e7os s\u00e3o indistingu\u00edveis das de um usu\u00e1rio real. <\/p>\n

Vantagens e desvantagens dos proxies residenciais<\/h2>\n

\nComo os proxies residenciais s\u00e3o endere\u00e7os IP fornecidos por provedores de internet dom\u00e9stica, a probabilidade de serem inclu\u00eddos em diversas listas negras e bloqueados \u00e9 extremamente baixa. Al\u00e9m disso, esses endere\u00e7os podem ser distribu\u00eddos de forma din\u00e2mica e mudam constantemente para cada usu\u00e1rio.<\/p>\n

Seu uso permite acessar com mais probabilidade o conte\u00fado necess\u00e1rio na internet: ningu\u00e9m bloquear\u00e1 solicita\u00e7\u00f5es de endere\u00e7os IP que est\u00e3o nas bases de provedores de internet residencial, em vez de empresas de hospedagem. Por esse mesmo motivo, proxies residenciais s\u00e3o mais adequados para tarefas de coleta e an\u00e1lise de dados. Portanto, as empresas que precisam coletar dados de v\u00e1rias fontes e contornar poss\u00edveis bloqueios utilizam esses proxies.<\/p>\n

Neste caso, proxies de servidor geralmente ganham em velocidade em compara\u00e7\u00e3o aos residenciais e tamb\u00e9m custam menos.<\/p>\n

O que escolher<\/h2>\n

\nAo escolher um proxy, deve-se basear nas tarefas. Se for necess\u00e1rio mascarar o endere\u00e7o IP e realizar opera\u00e7\u00f5es rapidamente com custo m\u00ednimo, e a possibilidade de bloqueio n\u00e3o \u00e9 uma preocupa\u00e7\u00e3o significativa \u2013 a op\u00e7\u00e3o ideal ser\u00e1 um proxy de servidor.<\/p>\n

Se, por outro lado, \u00e9 necess\u00e1rio uma ferramenta confi\u00e1vel para coleta de dados, com uma ampla escolha de geolocaliza\u00e7\u00f5es e m\u00ednimas chances de cair em uma lista negra ou bloqueio \u2013 os proxies residenciais se tornam mais convenientes.
