> It's 2020, the cost of an ipv4 address is more than $20 an address.
But arbitrary layers of NAT are free, so in practice this shouldn't actually block anyone. I haven't had a globally reachable IP address for any of my computers ever, and yet here I am on the web.
It may not matter in the developed world where this cost doesn't matter because infrastructure is cheap. There are still limits to how much this can scale as a solution no?
For a Country like India, surely this cost will matter especially for it's poorest citizens. The limits of this infinite scaling NAT will matter. That and the cost of an IP which I imagine will inflate much higher than $20 an address.
It's 2020, why isn't this a priority on the roadmap. I think it would have a much more meaningful impact to those that need it.
