|
Any-to-many communication model
|
Detailed explanation-1: -True, three of the characteristics of an IPv6 anycast address are delivery of packets to the group interface that is closest to the sending device, the same address for multiple devices (not hosts), and a one-to-many communication model.
Detailed explanation-2: -An IPv6 anycast address is an address that is assigned to a set of interfaces that typically belong to different nodes. Anycast addresses are syntactically indistinguishable from unicast addresses, because anycast addresses are allocated from the unicast address space.
Detailed explanation-3: -The global unicast IPv6 addresses are similar to IPv4 public addresses. These addresses can be used on the Internet. The big difference with IPv4 however, is that IPv6 has so much address space that we can use global unicast addresses on any device in the network.
Detailed explanation-4: -Changes from IPv4 to IPv6 are described in the following categories: Expanded routing and addressing capabilities – IPv6 increases the IP address size from 32 bits to 128 bits to support more levels of addressing hierarchy. In addition, IPv6 provides a greater number of addressable nodes.
