>False, the default behavior is the same as IPv4/NAT. The default behavior it is not the same as IPv4 with NAT, where the internet and local are different networks. >It is not unlike a random uuid or even a mac address in that the address is simply globally unique in nature, but not necessarily accessible unless you deliberately configure it to be, not unlike how one deliberately configures port forwarding in a local NAT based network firewall. The prefix the ISP gives to the router for to assign the IPv6 addresses to computers and devices it is the prefix of the unique uuid each one will get assigned. An unique IPv6 address is assigned to each one of these computers and devices, case contrary they would not be accessible from internet. If the firewall fails or if it's shut down, all get exposed to internet, because IPv6 it is designed to make every computer and device part of the internet network by default & design.
