I never noticed this, actually. The standard net.Dial(), for "historical reasons", just prefers IPv4 instead of relying on the local resolver. This prompted a "Wow, okay" from B. Fitzpatrick. (https://github.com/golang/go/issues/20911).

It looks like one can get around that by using the Lookup* methods first, but that is a hassle that will require some experimentation to make sure the behavior is right, e.g. with and without cgo and for unspecified listener addresses etc, for something that should ideally "just work".

Anyway, thanks for working around that. :/
