Are you talking about home or work network? If you have dual-stack gateway, then your LAN has should have IPv6 unless you deliberately disabled it. For simple networks, should just need to enable IPv6 on router. If you haven't disabled it on each machine, they are using site-local IPv6. I don't know which devices on my home network use IPv6, but I haven't had to enter IPv6 addresses anywhere. IPv6 networks are simpler. They do many things automatically that have to be entered manually. The big one is don't have to worry about subnet size or subnet masks; all subnets are /64 and effectively infinite. This doesn't matter for home network but it is big advantage for corporate networks.
