6to4 and 6in4 are not NAT. They're tunnels (VPNs) that allow two IPv6
nodes to talk to each other via an IPv4 backbone.

nat64 is NAT. It allows IPv6 endpoints to communicate with IPv4 endpoints.

nat44 is the IPv4 NAT you're used to.
nat444 is carrier NAT (translated once by the customer and once again
by the ISP, get it?)
