Detailed explanation-1: -Anycast addresses are used to deliver packets to the “nearest” interface, where nearness is defined as a routing parameter. The same can be done in IPv4, but not as elegantly. However, multicasts deliver to many interface destinations, while anycasts deliver to only one, although many might be reachable.
Detailed explanation-2: -For example, 192.5. 5.241 is an anycasted ip address and 212.71. 233.103 is a unicast ip address. Both are ipV4 addresses.
Detailed explanation-3: -Anycast is a network addressing and routing method in which incoming requests can be routed to a variety of different locations or “nodes.” In the context of a CDN, Anycast typically routes incoming traffic to the nearest data center with the capacity to process the request efficiently.
Detailed explanation-4: -An IPv6 anycast address uses the same address range as global unicast addresses. Each participating device is configured to have the same anycast address. For example, servers A, B, and C in Figure 4-14 could be DHCPv6 servers with a direct Layer 3 connection into the network.
