On the server side, everyone is moving behind CDNs that support IPv6 by default.

On the consumer home internet side, consumer ISPs are slowly one by one lighting up IPv6, and it just works since consumer routers are mostly auto-configure (often literally controlled by the ISP). Mobile is largely IPv6 already.

The biggest challenge is in corporate/academic/medium-size business networks where they have lots of obscure subnets and firewall rules and old software and hardware running a critical task under a dusty table somewhere.
