Registrador de internet regional RIPE NCC, respons\u00e1vel pela distribui\u00e7\u00e3o de endere\u00e7os IP na Europa, na \u00c1sia Central e na \u00c1sia Central, anunciou<\/a><\/noindex> sobre a distribui\u00e7\u00e3o do \u00faltimo bloco dispon\u00edvel de endere\u00e7os IPv4. Em 2012, a RIPE come\u00e7ou<\/a><\/noindex> a distribui\u00e7\u00e3o do \u00faltimo bloco \/8 de endere\u00e7os (cerca de 17 milh\u00f5es de endere\u00e7os) e reduziu o tamanho m\u00e1ximo das sub-redes atribu\u00eddas para \/22 (1024 endere\u00e7os). Ontem, o \u00faltimo bloco \/22 foi atribu\u00eddo e n\u00e3o restaram endere\u00e7os IPv4 dispon\u00edveis na RIPE.<\/p>\n

As sub-redes IPv4 agora ser\u00e3o atribu\u00eddas exclusivamente a partir do pool de blocos de endere\u00e7os retornados, que \u00e9 reabastecido por organiza\u00e7\u00f5es fechadas que possu\u00edam endere\u00e7os IPv4, pela transfer\u00eancia volunt\u00e1ria de blocos n\u00e3o utilizados ou pela retirada de sub-redes ap\u00f3s o fechamento de contas de LIRs. Os endere\u00e7os do pool de blocos retornados ser\u00e3o concedidos na ordem filas<\/a><\/noindex> de blocos n\u00e3o excedendo 256 (\/24) endere\u00e7os. Solicita\u00e7\u00f5es para entrar na fila s\u00e3o aceitas apenas de LIRs que anteriormente n\u00e3o receberam endere\u00e7os IPv4 (atualmente h\u00e1 11 LIRs na fila).<\/p>\n

Observa-se que a demanda por IPv4 pelos operadores \u00e9 contada em milh\u00f5es de endere\u00e7os. A implementa\u00e7\u00e3o ativa de tradutores de endere\u00e7os (CG-NAT<\/a><\/noindex>) e o mercado de revenda de endere\u00e7os IPv4 que surgiram nos \u00faltimos anos s\u00e3o apenas compromissos tempor\u00e1rios que n\u00e3o resolvem o problema global da escassez de endere\u00e7os IPv4. Sem a implementa\u00e7\u00e3o em larga escala do IPv6, o crescimento da rede global pode ser limitado n\u00e3o por problemas t\u00e9cnicos ou falta de investimentos, mas pela simples escassez de identificadores de rede exclusivos. <\/p>\n

De acordo com dados<\/a><\/noindex>, com base nas estat\u00edsticas de consultas aos servi\u00e7os do Google, a participa\u00e7\u00e3o do IPv6 se aproxima de 30%, enquanto um ano atr\u00e1s esse n\u00famero era 21%, e dois anos atr\u00e1s \u2014 18%. A maior taxa de utiliza\u00e7\u00e3o do IPv6 \u00e9 observada na B\u00e9lgica (49,8%), Alemanha (44%), Gr\u00e9cia (43%), Mal\u00e1sia (39%), \u00cdndia (38%), Fran\u00e7a (35%), EUA (35%). Na R\u00fassia, o n\u00famero de usu\u00e1rios de IPv6 \u00e9 estimado em 4,26%, na Ucr\u00e2nia \u2014 2,13%, na Rep\u00fablica da Bielorr\u00fassia \u2014 0,03%, no Cazaquist\u00e3o \u2014 0,02%.<\/p>\n

De acordo com estat\u00edsticas<\/a><\/noindex> da empresa Cisco, a participa\u00e7\u00e3o de prefixos rote\u00e1veis de IPv6 \u00e9 de 33,54%. O n\u00famero de usu\u00e1rios de IPv6 nos relat\u00f3rios da Cisco corresponde aproximadamente \u00e0s estat\u00edsticas do Google, mas informa\u00e7\u00f5es adicionais sobre o grau de ado\u00e7\u00e3o do IPv6 nas infraestruturas dos operadores tamb\u00e9m s\u00e3o fornecidas. Na B\u00e9lgica, a taxa de ado\u00e7\u00e3o do IPv6 \u00e9 de 63%, na Alemanha \u2014 60%, na Gr\u00e9cia \u2014 58%, na Mal\u00e1sia \u2014 56%, na \u00cdndia \u2014 52%, na Fran\u00e7a \u2014 54%, nos EUA \u2014 50%.
