+1. I recently misconfigured my router to a bad IPv6 setting and half my apps were failing but chrome and others would still work. Took me a couple days to figure out what was going wrong.

@dlubarov , @JakeWharton do you folks happen to be working on bringing Happy Eyeballs support to OkHttp? There are more DHCPv6-based IPv6 networks every day, especially in corporate settings, and the ability to pick the better transport in parallel will greatly benefit user experience.

It’s possible to implement this manually by making two HTTP requests yourself and picking the one that returns first. Doing it inside of OkHttp is more difficult. For example, what should the interceptors see? We might be able to do further work later to unblock this, but for now it seems very difficult to do well.
