Slaac does everything for you. You get dynamic public addresses that change (you can disable if you please). Nothing to deal with, just open a firewall port if you want to receive traffic
Ideally, using just IP6 would be simpler, as every device gets a global address. Then you don’t need to mess with NAT, port forwarding and all that bullshit. Every device having multiple addresses just complicates things.
A lot of the world, especially Africa and south America, was somewhat later in adopting the Internet and has a much smaller supply of IPv4 addresses. People with ISPs there need IPv6 to be directly connectable without CGNAT
PXE, or network boot. It is basically never used (and rarely enabled, if ever, by default) by the individual, but can be helpful in, for example, a large scale OS deployment. Say IT has to get their corporate image version of Windows 10/11 installed on 30 new laptops. They could write a ton of flash drives, but it’d be easier to just host a PXE boot server and every laptop just listen to them.
V6 specifically in that instance would just be for the reason of “we need to move away from v4 anyways”
When does a machine ever need IP6?
Ipv6 is the replacement for ipv4. There now exist networks without ipv4
To expand on this, we have functionally ran out of IPv4 addresses. Meaning IPv6 addresses are required.
Not only that, but ipv6 makes networking easier and less complicated. No longer, needing port forwarding or NAT, amongst other improvements
It’s that necessarily a good thing?
I remember suddenly needing a firewall on my PC back in the days of the Blaster worm.
Do we really want all those crappy IoT devices open on all ports to the general internet?
I’d be fucked if I had to deal with IPv6 at home. Give me NAT, port forwarding and a dynamic public address that changes.

Only for the internet, not private space
No shit.
But a private Lan will never need it.
There are 4 billion+ possible IP v4 addresses, nearly 600 million in the current private range.
Show me a private network with 600 million devices.
There’s no reason a device that doesn’t have a direct internet connection needs IP6.

For private address space you never need 6.
When it is running in a modern, I.e. IPV6 network?
None of you have given any reason a private address space needs 6

PXE works on ipv4, did gobs of it over the years.
