Thank you. So in a way if the carriers upgrade their infrastructure there would be a decrease in privacy because then it’s a one-to-one correspondence between IP address and customer, but then the customer would have the ability to host servers? The one scenario where the industry dragging their heels on upgrading is actually good for the consumer (in some respects) lol

Adding commas to that number: 4,294,967,296 addresses. More humans that IP address seems like a huge miscalculation in the internet infrastructure

Who could've thought in 1981 that more than a few thosand universities would ever like to connect to the then 250 machines big ARPANET. With 4 billion addresses, there was plenty of headroom at the time.

In 50 years, when the last ISP finally switches to IPv6, we'll be wondering how short sighted we were as now every pencil has an IP address in the interplanetary compu-global-hyper-meganet.

We planned for that. We should be fine at least until we are an interstellar species. We could assign an IPV6 address to EVERY ATOM ON THE SURFACE OF THE EARTH, and still have enough addresses left to do another 100+ earths. It isn’t remotely likely that we’ll run out of IPV6 addresses at any time in the future.

Goverments (depending on juristiction) have laws requiering isp's to keep track of cgnat port combos. So not only is there no privacy from ipv4 cgnat. Now the isp must also spend a lot of money on the nat state tracking database.
If you need that kind of privacy, use a vpn and the tor onion network.

Ah of course i was gonna say even with a cgnat they would have some way of identifying the traffic.

It's a bit more complicated than that. Governments still spy on an IPv4 address, but because that address is shared, it's spying on everyone behind it. At least with IPv6, it'd be targeted.
