第8次更新第二题答案错误

此题应该选ABF。A是静态NAT-PT，B是隧道技术，F是双栈技术
此题以前出现过，当时题目选项没有照全，那个答案也是错误的，如下图

再次更正，答案ABF

BDF, D 应该是对的。http://en.wikipedia.org/wiki/IPv6#Dual_IP_stack_implementation 中有这一段话：
Proxying and translation for IPv6-only hosts
Main article: IPv6 transition mechanisms
After the regional Internet registries have exhausted their pools of available IPv4 addresses, it is likely that hosts newly added to the Internet might only have IPv6 connectivity. For these clients to have backward-compatible connectivity to existing IPv4-only resources, suitable IPv6 transition mechanisms must be deployed.

One form of address translation is the use of a dual-stack application layer proxy server, for example a web proxy.

NAT-like techniques for application-agnostic translation at the lower layers in routers and gateways have been proposed. The NAT-PT standard was dropped due to a number of criticisms,[42] however more recently the continued low adoption of IPv6 has prompted a new standardization effort under the name NAT64.
