Your company is researching a new application that runs over IPv6， but part of it must still have IPv4 support. Your company uses a traditional IPv4 network. Your plan is not to run IPv6 over the whole network， but to segment parts of the network or even to operate simultaneously with IPv6 and IPv4. You must make a brief presentation about IPv6 technology to the board of technical directors. Which three of these items could be part of your presentation？ （）A、 Tunnel IPv6 over IPv4 to connect far-end IPv6 networksB、 Explain why configuring IPv4 and IPv6 at the same time over the same LAN interface is not possibleC、 Explain why configuring IPv4 and IPv6 at the same time over the same LAN interface is possibleD、 What is the meaning of EUI-64 and how does it work？E、 Tunnel IPv4 over IPv6 to connect far-end IPv4 networks.
