Describe NAT64?
Tacks the bytes of an IPv4 address onto the end of an IPv6 address for network traversal.
Handles the traffice between IPv4 and IPv6.
Otherwise, IPv6 has no use for NAT.
Is it hard to set up DNS with IPv6?

Briefly describe why DHCP is necessary for IPv6?
DHCP is still important in IPv6, but in slightly different ways than it was in IPv4.
DHCPv6 still works like traditional DHCP in that you have to configure a DHCPv6 server.
This DHCPv6 server works in one of two modes: stateful or stateless.

stateful
