Considerando a mudan\u00e7a para IPv6? Pode ser prematuro para usu\u00e1rios de proxy.<\/p>\n\n\n\n

Vis\u00e3o geral: proxies IPv4 e IPv6<\/h2>\n\n\n\n

No cen\u00e1rio digital atual, o IPv4 continua a ser o protocolo IP predominante. Quando voc\u00ea est\u00e1 no mercado de servidores proxy, \u00e9 prov\u00e1vel que encontre aqueles baseados em IPv4. No entanto, as redes proxy baseadas em IPv6 est\u00e3o gradualmente ganhando for\u00e7a. Este guia visa elucidar os contrastes entre os proxies IPv4 e IPv6 e as implica\u00e7\u00f5es de escolher um em vez do outro.<\/p>\n\n\n\n

A ess\u00eancia de um endere\u00e7o IP<\/h2>\n\n\n\n

Um endere\u00e7o IP (Internet Protocol) \u00e9 um r\u00f3tulo num\u00e9rico que identifica exclusivamente dispositivos conectados \u00e0 Internet. Este r\u00f3tulo \u00e9 atribu\u00eddo se voc\u00ea estiver usando uma conex\u00e3o com fio, Wi-Fi, redes celulares ou qualquer outra forma de conectividade com a Internet. Ele atua como um identificador que permite que os dispositivos interajam entre si na web.<\/p>\n\n\n\n

O que \u00e9 um proxy IPv4?<\/h2>\n\n\n\n

Um proxy IPv4 utiliza o padr\u00e3o IPv4 (Internet Protocol vers\u00e3o 4). Como o \u201cv4\u201d indica, esta \u00e9 a quarta itera\u00e7\u00e3o do protocolo IP. O protocolo IPv4 tem sido a base da Internet p\u00fablica desde a sua cria\u00e7\u00e3o, e o seu espa\u00e7o de endere\u00e7os permite aproximadamente 4,3 mil milh\u00f5es de endere\u00e7os IP \u00fanicos.<\/p>\n\n\n\n

Limita\u00e7\u00f5es do IPv4:<\/h3>\n\n\n\n
    \n
  1. Escassez de endere\u00e7os<\/strong>: A principal desvantagem do IPv4 \u00e9 seu espa\u00e7o de endere\u00e7o limitado. \u00c0 medida que a Internet das Coisas (IoT) se expande, 4,3 mil milh\u00f5es de endere\u00e7os s\u00e3o insuficientes.<\/li>\n\n\n\n
  2. Mito dos Proxies Virgens<\/strong>: Com a escassez de endere\u00e7os IPv4, a no\u00e7\u00e3o de IPs \u201cvirgens\u201d ou n\u00e3o utilizados \u00e9 em grande parte uma jogada de marketing.<\/li>\n<\/ol>\n\n\n\n

    Significado dos proxies m\u00f3veis<\/h2>\n\n\n\n

    Devido \u00e0 escassez de endere\u00e7os, os ISPs (Provedores de Servi\u00e7os de Internet) recorreram a t\u00e9cnicas como Carrier Grade Network Address Translation (CGNAT). Isto \u00e9 particularmente prevalente em redes m\u00f3veis. CGNAT permite o mapeamento de v\u00e1rios endere\u00e7os de rede privada para um \u00fanico endere\u00e7o IP p\u00fablico.<\/p>\n\n\n\n

    Vantagens dos proxies m\u00f3veis:<\/h3>\n\n\n\n
      \n
    1. Menos probabilidade de ser bloqueado<\/strong>: quando v\u00e1rios usu\u00e1rios compartilham um \u00fanico IP, banir esse IP pode afetar v\u00e1rios usu\u00e1rios, tornando os IPs m\u00f3veis menos propensos a bloqueios.<\/li>\n\n\n\n
    2. Otimizado para plataformas m\u00f3veis<\/strong>: Grandes plataformas como Instagram e Facebook projetam seus servi\u00e7os pensando nos usu\u00e1rios m\u00f3veis, tornando os proxies m\u00f3veis ainda mais valiosos.<\/li>\n<\/ol>\n\n\n\n

      O que \u00e9 um proxy IPv6?<\/h2>\n\n\n\n

      Um proxy IPv6 \u00e9 um intermedi\u00e1rio que emprega o padr\u00e3o IPv6 (Internet Protocol vers\u00e3o 6). Introduzido em 2012, o IPv6 foi projetado para mitigar as limita\u00e7\u00f5es do IPv4, principalmente a falta de espa\u00e7o de endere\u00e7o. O IPv6 possui uma capacidade de endere\u00e7o de aproximadamente 340 undecilh\u00f5es de endere\u00e7os exclusivos, eliminando efetivamente o problema de escassez.<\/p>\n\n\n\n

      Por que a ado\u00e7\u00e3o do IPv6 est\u00e1 atrasada:<\/h3>\n\n\n\n
        \n
      1. Incompatibilidade<\/strong>: O IPv6 n\u00e3o \u00e9 compat\u00edvel com vers\u00f5es anteriores do IPv4, necessitando de uma revis\u00e3o abrangente da infraestrutura da Internet.<\/li>\n\n\n\n
      2. Suporte do site<\/strong>: 71% dos 500 principais sites da Alexa, incluindo gigantes como Amazon e Twitter, ainda n\u00e3o suportam IPv6.<\/li>\n<\/ol>\n\n\n\n

        Disponibilidade de proxies IPv6 residenciais<\/h2>\n\n\n\n

        At\u00e9 o momento, os principais provedores de proxy residencial ainda n\u00e3o oferecem solu\u00e7\u00f5es baseadas em IPv6, embora possam existir provedores de nicho em f\u00f3runs especializados como o BlackHatWorld. Geralmente, os provedores de servi\u00e7os evitam incorporar o IPv6 em seus pools de proxy.<\/p>\n\n\n\n

        O IPv6 \u00e9 a escolha certa para servidores proxy?<\/h2>\n\n\n\n

        Embora os proxies de datacenter IPv6 sejam mais baratos e abundantes, eles apresentam seu pr\u00f3prio conjunto de desvantagens.<\/p>\n\n\n\n

        Contras dos proxies IPv6:<\/h3>\n\n\n\n
          \n
        1. Compatibilidade limitada de sites<\/strong>: Muitos sites ainda operam exclusivamente em IPv4.<\/li>\n\n\n\n
        2. Bloqueio de alcance<\/strong>: se um endere\u00e7o IPv6 de uma sub-rede for colocado na lista negra, \u00e9 comum que todo o intervalo seja banido.<\/li>\n<\/ol>\n\n\n\n

          Conclus\u00e3o<\/h2>\n\n\n\n

          No cen\u00e1rio atual, os proxies IPv4 oferecem suporte mais amplo a sites e endere\u00e7os residenciais de maior qualidade. No futuro pr\u00f3ximo, o IPv4 continuar\u00e1 sendo a escolha mais confi\u00e1vel para usu\u00e1rios de proxy. Portanto, o fasc\u00ednio dos proxies IPv6 \u201cvirgens\u201d deve ser encarado com certo ceticismo.<\/p>","protected":false},"excerpt":{"rendered":"

This address is essential for devices to locate each other and establish a connection over the internet.<\/span>"},{"question":"What is a proxy server?","answer":"A proxy server acts as an intermediary between your device and the internet. It forwards your web requests and returns the responses, effectively masking your original IP address.<\/span>"},{"question":"Why would I need to use a proxy server?","answer":"Proxy servers offer various benefits such as anonymity, improved security, faster loading times via caching, and the ability to bypass geo-restrictions or access-blocked websites.<\/span>"},{"question":"What is an IPv4 proxy?","answer":"An IPv4 proxy uses the fourth version of the Internet Protocol (IPv4) to route your internet traffic. It remains the most widely used IP protocol for now, despite its limitations, such as the scarcity of available addresses.<\/span>"},{"question":"What is an IPv6 proxy?","answer":"An IPv6 proxy uses the sixth version of the Internet Protocol (IPv6). This protocol was developed to solve the limitations of IPv4, primarily its limited number of available addresses.<\/span>"},{"question":"Why is IPv6 adoption slower than expected?","answer":"The primary reason is incompatibility. IPv6 is not backward-compatible with IPv4, requiring a complete overhaul of existing internet infrastructure for universal adoption.<\/span>"},{"question":"Can I find residential IPv6 proxies?","answer":"As of now, major residential proxy providers do not offer IPv6-based solutions. However, some specialized vendors might offer them on platforms like BlackHatWorld.<\/span>"},{"question":"Why are mobile proxies valuable?","answer":"Mobile proxies use technologies like Carrier Grade Network Address Translation (CGNAT) that map multiple private network addresses to a single public IP. This makes these IPs less likely to be blocked and highly effective for mobile-first platforms like Instagram and Facebook.<\/span>"},{"question":"Should I opt for an IPv4 or IPv6 proxy?","answer":"IPv4 proxies offer better website compatibility and are generally more reliable. IPv6 proxies are cheaper but come with limitations such as limited website support and the risk of range blocking.<\/span>"},{"question":"What is the myth of 'virgin' proxies?","answer":"The term 'virgin' refers to unused proxy IPs. While this term is often used in marketing, the scarcity of IPv4 addresses makes it nearly impossible to find genuinely virgin IPv4 proxies.<\/span>"}]},"_links":{"self":[{"href":"https:\/\/oneproxy.pro\/pt\/wp-json\/wp\/v2\/docs\/490250","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/oneproxy.pro\/pt\/wp-json\/wp\/v2\/docs"}],"about":[{"href":"https:\/\/oneproxy.pro\/pt\/wp-json\/wp\/v2\/types\/docs"}],"version-history":[{"count":0,"href":"https:\/\/oneproxy.pro\/pt\/wp-json\/wp\/v2\/docs\/490250\/revisions"}],"wp:attachment":[{"href":"https:\/\/oneproxy.pro\/pt\/wp-json\/wp\/v2\/media?parent=490250"}],"wp:term":[{"taxonomy":"docs-categories","embeddable":true,"href":"https:\/\/oneproxy.pro\/pt\/wp-json\/wp\/v2\/docs-categories?post=490250"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
