Re: Does IPv6 preclude use of a NAT gateway?

Interesting. I have a network printer which I, quite naturally, plug
into my NAT/router so it's in my private 192.168.0. network with my

IPv6 but for now let's assume that it does. How would this kind of
setting fit into a pure IPv6 world? Of course I want my printer to be
still private and not available to the whole Internet. I need some kind
of private network. How will I build that?

You have private IPv6 addresses as well. They are called Unique Local Unicast (fc00::/7 (fc… and fd…)). For now you only can use addresses starting with fd.

But since there is no NAT for IPv6, if your printer needs internet access (e.g. firmware updates) and you don’t have a HTTP proxy (if your printer supports a proxy), your printer could not connect to the internet. It would need a public IPv6 address.

Shade and sweet water!
