COMPUTER NETWORKING

Detailed explanation-1: -In IPv6, there’s no longer any broadcast – There’s only multicast, unicast and anycast. In IPv6 all nodes are required to support multicast. Without multicast, many services that you need will simply not work. There’s a constant hum from the network on the multicast channels.

Detailed explanation-2: -Broadcast has been removed because Multicast is better, simply put. Multicast didn’t exist when IPv4 was created. Switching was barely a thing as well, so unicast and broadcast were almost the same thing, in terms of how they caused the hubs on a LAN segment to behave.

Detailed explanation-3: -Which statement(s) about IPv6 addresses are true? Explanation: In order to shorten the written length of an IPv6 address, successive fields of zeros may be replaced by double colons. In trying to shorten the address further, leading zeros may also be removed.

Detailed explanation-4: -The address fields in IPv6 packets are 128 bits long, meaning 2 to the power 128 or 2128 addresses. That’s 340, 282, 366, 920, 938, 463, 463, 374, 607, 431, 768, 211, 456 addresses. This is a number beyond human comprehension.
