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?)
More accurately: NAT44 is consumer NAT you're used to. LSN/CGN is NAT at the carrier level. DS-LITE is native IPv6 with private IPv4 tunneled over IPv6 to reach an LSN/CGN for IPv4 connectivity. NAT444 is NAT44 + LSN/CGN Owen
