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

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

EXPLANATION

With IPv6, devices can build a link-local address automatically.
But notice this address is only used for communications within the local subnetwork, routers do not forward these addresses.
