APNIC reminds us that "there are now a large number of ISPs, data centres, cloud services, and software that now support IPv6" and "enabling IPv6 can be as simple as clicking a button on your WiFi router."
I turned it on, with Comcast I received an IPv6 route but no DNS server. Fortunately, Google Public DNS has unmemorable addresses, which I was able to configure manually.
2001:4860:4860::8888
2001:4860:4860::8844
It works. "There's only one thing left for you to do: Turn it on!"

My VPN service explicitly turns off IPv6 in order to make sure nothing leaks out via that path and I'm good with that.
Then you should block outgoing the Teredo port (3544) and the IPv6 encapsulation protocol (41). I'm finding all sorts of nasty stuff happening on the LAN side.
