V6 still not supported

Yes, you are right. And gradually IPv4 was improved and fixed.
We learned how to defend L2. CIDR was added (with should be thing
from the begining instead of netmasks, but who could forsee...)

And in case of IPv6 it seems that all that experience was throwed out
of window. Design was much different that IPv4, adding new issues.
I have feeling that IPv6 was made by people who were NOT running networks.

The big question is, what we can do that to fix IPv6 problem.
I have no clue at all.. Im personally biased against IPv6.

As somebody who designed IoT things back when v6 was being designed, my only
question was whether it would get deployed, not whether it was too complex. It
was honestly a lot easier than a completely new protocol stack like appletalk or

I don't see what the OS layer has to do with anything. An operating system that
doesn't get patches is even worse than app level code that doesn't.

There were tons of things that were slapped onto IP that were basically
experimental like ARP and bootp. CIDR didn't even exist back then.

Also: security, for example, was not an already fixed problem. Far from it.
