How to get into IPv6 slowly...

I think it is time for me to slowly get into IPv6. Since you guys helped me in a very good way with my HASS questions, i thought i try it again :)

• With IPv6 you don't need NAT and DHCP because every device has got a unique IP address. Right? But does that mean that you need to put a firewall on every device? Or do we still use one outgoing IPv6 address to go to the internet via a router?

• if we still use a router with one outgoing address than we will also still need to use port forwarding right? And if we still use one outgoing address we would still need to do something like NAT right?

• IPv6 is not backwards compatible so if you would only have an IPv6 connection you will not be able to open an IPv4 only website. This is part of the reason why the transition is going so so slow right?

• When it comes to WAN IPv6 connections, what does DS-Lite, Full Dual Stack and Native IPv6 mean? What is the difference?

• When looking at a Windows server domain dhcp server, you are able to create a DHCP for IPv6. Why is that?

• Does (local )DNS still work still the same as it does with IPv4? At domain DNS level you don't create an A record anymore but an AAAA record right? But all the other types of records still function the same?

• How do you easily read the an IPv6 long long address? With IPv4 you can "read" the subnet and ip range for example 192.168.100.0/24.

I hope you guys are able to point me in the right direction. Of course i tried Google, but i often came across a lot of info but not exactly what i meant.

Many thanks in advance!
