I’ve talked to several network engineers over the years about IPv6, engineers that work as hands on with actual production infrastructure as you can get. And they all said that IPv6 would likely never be fully adopted.
But why ?
I am not a full network engineer so take my opinion with a grain of salt. From what I understand, NAT with IPv4 works really really well to mitigate IPv4 address exhaustion. Then there’s an issue with the amount of extra processing switches and routers need to do IPv6, we’re going from 32 bits to 128 bits which is a huge increase and for switches and routers that are handling packets as fast as technically possible with a low amount of resources typically, that’s a not insignificant hurdle.
It’s just easier to do IPv4 in every way, plus that’s what the world’s been using and is used to.
