[Question] what exactly is hard about adopting IPv6?? (programming.dev)

I mean on a technical level. Are the devices that make up the infrastructure of the internet hardwired with IPv4? Is the firmware on these devices impossible to upgrade remotely?

If it's just a matter of software or firmware then adoption should only take like a year but clearly that isn't the case. So what specifically is stopping us?

Nothing, it has never been a technical problem it has always been a business problem. Why spend engineer time and money on deploying V6 when v4 is working perfectly fine and we are not approaching exhaustion of v4 space available for our customers.

Ugh, my job requires us to use their VPN but all IPv6 traffic leaks out of the tunnel because they can’t be bothered to at least blackhole it. I feel like I’m living in 1995 at work.

Same, we started having issues recently when MS enabled IPv6 on their login page. Now some users who are connected to the VPN aren't able to login because the login request is not coming from a trusted ipv4 address in conditional access .
