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。
