Detailed explanation-1: -5. Which among the following features is present in IPv6 but not in IPv4? Explanation: There is an anycast address in IPv6 which allows sending messages to a group of devices but not all devices in a network. Anycast address is not standardized in IPv4.
Detailed explanation-2: -IPv4 uses class-type address space for multicast use (224.0. 0.0/4). IPv6 uses an integrated address space for multicast, at FF00::/8. IPv4 uses “broadcast” addresses that forced each device to stop and look at packets.
Detailed explanation-3: -The correct answer is 128 bit. Internet Protocol version 6 is the most recent version of the Internet Protocol. IPv6 uses a 128-bit address, theoretically allowing 2128, or approximately 3.4×1038 addresses.
