第19题:
IPv6 allows a host to create its own IPv6 address that will allow it to communicate to other devices on a network configured via DHCP. IPv4 does not provide a similar capability for hosts.
IPv6 provides for more host IP addresses but IPv4 provides for more network addresses.
Hosts can be configured to receive both IPv4 and IPv6 addresses via DHCP.
Host configuration options for IPv4 can be either statically assigned or assigned via DHCP.Host configuration options for IPv6 can be statically assigned only.
IPv4 and IPv6 addresses c an be simultaneously assigned to a host but not to a router interface.
