NAT444...NAT behind NAT behind NAT on the ISP level.

NAT444 is two levels of NAT, not three. Each digit refers to an addressing domain, not a translation layer. The translation layers are the invisible boundaries between the digits. In NAT444, all the addressing domains are IPv4, hence three "4"s.
