The IPv4 exhaustion is far more gnarly in developing countries. Something on the scale of hundreds of people sharing one IPv4 address.
If I want to get a public IPv4 address from my ISP, I have to spend extra. Some ISPs in my country simply don’t give public IPv4 addresses anymore. They have completely exhausted their pool.
