O IPv6 é a nova versão do IPv4 (32 bits) que foi desenvolvido para
solucionar definitivamente o problema da escassez de endereços na
Internet. O IPv6 possui 128 bits, permitindo o endereçamento de:
340.282.366.920.938.463.463.374.607.431.768.211.456
Esse número equivale a:
 79 Trilhões de Trilhões de Vezes a Quantidade Atual do IPv4 (4 bi)

Dentre as principais vantagens do IPv6, temos:
• Quantidade “Ilimitada” de Endereços
• Autoconfiguração de Endereços (SLAAC)
• Cabeçalho Simplificado e de Tamanho Fixo (40 bytes)
• Menor Carga de Processamento dos Cabeçalhos nos Roteadores
• Distribuição Organizada de Endereços
• Suporte Integrado à Segurança via IPSec
• Suporte Integrado à Mobilidade via MIPv6
• Dispensa a Adoção de NAT

• A distribuição de endereços para os computadores
que se conectam à Internet é coordenada por
autoridades de abrangência mundial, de maneira a
evitar sua duplicação e/ou má distribuição.
• A autoridade local responsável pela distribuição dos
Endereços IPs aos provedores no Brasil é o NIC.br
(Núcleo de Informação e Coordenação do Ponto BR).

2011 – Ano da “Contradição” p/ Internet:
• Em 2011 os estoques de endereços IPv4 da IANA (autoridade
mundial da Internet) se esgotaram. Nesse mesmo ano
esgotaram os endereços IPv4 da APNIC, autoridade regional da
Internet (RIR) na Ásia e Pacífico;
• Também em 2011 a ONU declarou a Internet como um direito
fundamental dos homens por ser uma ferramenta
imprescindível para o exercício da liberdade de expressão;
