Most people run the modem/router combo that their ISP provides them. The ISP can flash that modem remotely to upgrade it to IPv6. As far as I know, that's how Comcast in the US managed to deploy ipv6 massively. It often surprised me that in some small US towns, I'd be in AirBNBs or B&B, and they had IPv6. In my neighbourhood in Canada, looking at the wifi routers, 80% of my neighbours are running the default configuration of their ISP. Also, people need to replace their modems more often than we think. In the past 5 years we had the switch from 5mbps DSL to FTTO (25-30mbps) and now the switch to FTTH. A neighbour switched from 5mbps DSL to FTTH, for basically the same price (but the same ridiculously low monthly quota). He's using FTTH for an empty house to connect his alarm system to the monitoring company. In 6-12 months (rumours were 2017-Q2 unless they * again), when Bell finally decides to enable IPv6, that network will be IPv6-enabled.
