For home users and non-professionals, IPv6 is simpler than IPv4. Every device autoconfigs selecting its own address via SLAAC. No DHCP needed. No need to understand NAT and no dealing with subnets. Especially when mDNS is in the mix and every device gets its own .local domain, which already happens with iOS, macOS and Windows devices (plus Linux with avahi), it is dead simple to have a very reliable local network.

Ditching Ethernet broadcast that hit every single interface on a network when you only wanted to communicate with a single device on a specific protocol is a big win. Getting rid of Subnets by making the smallest possible subnet infinitely large eliminated 90% of network confusion around subnets. Privacy based IP addresses also a nice addition. After working with IPv6 for 10 or so years, you really grew to appreciate what an architectural advantage it has over IPv4. As for deploying it? I dunno - I just plug my Ubuntu laptop into a WiFi Network and it just seems to work. I'm pretty sure the comcast routers I've connected to have had zero configuration beyond what they can pick up connecting to comcast. In the future - people (other than say Network Engineers working for IT) probably won't even discuss things like "IP" addresses.

So, a common home setup is to plug a fancy router behind the ISPs useless modem router. What happens is, IPv4 works out of the box. IPv6 doesn't work, because the fancy router doesn't get a big enough subnet from the useless ISP modem.

  My piece of shit useless ISP modem/router (from Spectrum, one step sideways from Comcast in quality) supports IPv6 out of the box. 0 effort. Getting it to stay working for an entire week without a reboot? Seems to be impossible. But IPv6 just works.

    Yeah. My useless ISP router supports it as well here. But it doesn't work when there's a second router in between. Something to do with Prefix Delegation not working, supposedly. And the ISP router by itself has zero controls for IPv4 DHCP, and so on, so it's absolutely useless by itself.

  My ISP just rolled out IPv6 a couple of weeks ago. I was pretty excited until I learned WSL2 doesn’t support IPv6.
