You can use Charter's 6rd service to get a /64 tunnel at home. They're only rolling out IPv6 to fiber business customers right now. Friend who worked there said the last modem rollouts were so they could do step 1: management of modems over v6.
So it shouldn't be too far off, but you never know...
You can configure a local IPv6-only network with macOS Server for the purpose of testing. You will see it as an access point on your device or simulator.
