You've been asked to move from IPv4 to IPv6. What is a valid reason for adopting IPv6 over IPv4?

• Telnet access does not require a password
• Change of destination address in the IPv6 header
• No broadcast
• Change of source address in the IPv6 header 

EXPLANATION

IPv6 does not implement traditional IP broadcast, and therefore does not define broadcast addresses. In IPv6, the same result can be achieved by sending a packet to the link-local all nodes multicast group which is analogous to IPv4 broadcast.

An IP address serves the purpose of identifying an individual network interface of a host, locating it on the network, and thus permitting the routing of IP packets between hosts. ... In contrast to IPv4, which defined an IP address as a 32-bit value, IPv6 addresses have a size of 128 bits.
