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?
Follow up question: why would I spend a bunch of extra time adapting something that honestly isn’t useful on the modern web? As it turns out, each device doesn’t need its own public IP. We have NAT which work fine and is potentially more secure and private.
