A network engineer would know how to NAT in IPv6, and wouldn't say an untrue statement like "there is no ability to NAT with IPv6".
Are you a network engineer?
I wouldn't advertise my title as "network engineer" but having a strong understanding networking and network design has been a big part of my jobs for the last 20 years or so.
I engineer and design network device drivers and network protocol stacks.
NAT is a terrible network protocol. The correct protocol would have been a DHCP extension giving you a 49-bit address where your IPv4 address constitutes a /32 with a 17-bit unique local address.
Fascinating. Would love to know more if you have a link.
