问题 Which two statements describe characteristics of IPv6 unicast addressing?

选项 A、        Global addresses start with 2000::/3.
B、        Link-local addresses start with FE00:/12.
C、        Link-local addresses start with FF00::/10.
D、        There is only one loopback address and it is ::1.
E、        If a global address is assigned to an interface, then that is the only allowable address for the interface.

答案A,D

解析 ipv6的常规问题,globaladdress的其实段位2000::/3这个是定义好了的,D选项说的是换回地址,也就是ipv4的127.0.0.1这个类似的.所以D正确。
