The IPv6 protocol is the most recent version of the Internet Protocol (IP).IPv6 includes several new features related to both addressing and routing.Which of the following features of IPv6 most directly increases the scalability of the Internet?Choose 1 answer:Choose 1 answer:(Choice A)   The IP v6 protocol strongly recommends the use of IPSec, a protocol that adds a layer of encryption to IP packets.AThe IP v6 protocol strongly recommends the use of IPSec, a protocol that adds a layer of encryption to IP packets.(Choice B)   The IPv6 packet includes extension headers, a way to extend the protocol to support future features that do not yet exist in the protocol.BThe IPv6 packet includes extension headers, a way to extend the protocol to support future features that do not yet exist in the protocol.(Choice C)   Each IPv6 address is a 128-bit number. That means there are   ( ) possible addresses for Internet-connected computing devices.CEach IPv6 address is a 128-bit number. That means there are   ( ) possible addresses for Internet-connected computing devices.(Choice D)   The IPv6 header includes a way to specify which flow a packet belongs to. That can be used by routers to handle the packets for particular flows differently from packets in other flows, such as prioritizing a flow for a real-time application.DThe IPv6 header includes a way to specify which flow a packet belongs to. That can be used by routers to handle the packets for particular flows differently from packets in other flows, such as prioritizing a flow for a real-time application.(Choice E)   The IPv6 header puts the most important information at the very beginning and moves the less important information to the end, enabling routers to more quickly decide how to forward packets.EThe IPv6 header puts the most important information at the very beginning and moves the less important information to the end, enabling routers to more quickly decide how to forward packets.
