alt Hacker News30 years on and if I have a machine with an ipv6 only network and run
"ping 1.1.1.1"
it doesn't work.
If stacks had moved to ipv6 only, and the OS and network library do the translation of existing ipv4, I think things would have moved faster. Every few months I try out my ipv6 only network and inevitably something fails and I'm back to my ipv4 only network (as I don't see the benefit of dual-stack, just the headaches)
Sure you'd need a 64 gateway, but then that can be the same device that does your current 44 natting.

This works if you have 464xlat turned on. It's mostly used by phones though.

There are lots of places that have IPv6-only networks and access IPv4 through NAT64. It makes sense for new company networks that can control what software gets installed.
The main limitation is software that only supports IPv4. This would affect your proposed solution of doing the translation in the stack. There is no way to fix an IPv4-only software that has 32-bit address field.
