I remember doing an IT course over a decade ago and learning about IPv6 taking over, honestly surprised it hasn't yet. I just looked it up and apparently they came up with it in 1998. How is it taking so long? Is there some technical reason it's harder or something? Does the extra address size mean a not so great trade off in traffic or something?
note: I did study a bit of networking and IT but have forgotten everything mostly and work in a different field, thus my ignorance.
Even tough IPv6 is technically superior to IPv4 for the network operator it doesn't have clear benefits for home users.
Having global addresses instead of NAT means less control over your LAN and these unique public addresses can track users more accurately.
is there any reason why we can't still use NAT with IPv6? it seems like that would solve at least some of the problems.
It is possible, it's just not generally supported be ISP routers. Also there is a possibility of performance issues since IPv4 NAT often relies on hardware acceleration which might not work for NAT6.
