第5题：

what is anycast address （Ipv6）？

正确答案:anycast is used for one-to-nearest communication. Anycast is a mechanism that delivers a packet to an anycast address to the nearest node member of the anycast group. An anycast address represents a service rather than a device， and the same address can reside on one or more devices providing the same service.

• A、There are four types of IPv6 addresses: unicast, multicast, anycast, and broadcast.
• B、A single interface may be assigned multiple IPv6 addresses of any type.
• C、Every IPv6 interface contains at least one loopback address.
• D、The first 64 bits represent the dynamically created interface ID.
• E、Leading zeros in an IPv6 16 bit hexadecimal field are mandatory.
