Thank you for failing to point out where I am wrong.

Not at all.

Instead, IPv6 is damaged a lot because of ATM based on so nice and
clean OSI model.

A physical limitation and an operational reality is that we
can not remember 16B addresses.

As I warned that IPv6, as was, is not operational about ten
years ago, it's not my responsibility to try to make IPv6
operational within a decade or two.

Instead, I am interested in the fact that IPv4 scales well
forever with end to end transparency, if port numbers, which
may be 16b, 32b or 48b long, are used for routing.

My most recent research result is how to modify client IPv4
stack to achieve end to end transparency for clients behind
UPnP capable NAT.
