[GTER] ICANN adds IPv6 to root servers

[Frederico A C Neves]

O título da matéria é ambíguo e ai reside a confusão.

O que agora é permitido é a solicitação de inclusão de registros do
tipo AAAA para as delegações na zona da raiz.

 > dig @a.root-servers.net jp ns
 ...
 ;; ANSWER SECTION:
 jp.                     2D IN NS        E.DNS.jp.
 ...
 ;; ADDITIONAL SECTION:
 E.DNS.jp.               2D IN AAAA      2001:200:0:1::4
 E.DNS.jp.               2D IN A         192.50.43.53
 ...

Os root servers ainda não tem glue AAAA adicionado para eles (zona
root-servers.net) e isto ainda deve levar algum tempo. A raiz permite
a delegação mas o transporte ainda não é ofertado em v6.

Esta alteração no fundo não traz grande benefício pois em caches que
respeitam o protocolo, esta informação é sobrescrita quando da
obtenção da resposta do servidor autoritativo. Todas as zonas que
vinham solicitando esta alteração já incluam estes glues a muito
tempo.

Quanto ao Registro.br nós permitimos AAAA para todas as zonas que
controlamos desde 12/2002, mas como na raiz, ainda não temos transporte
v6 para os servidores autoritativos.
