When `autoSelectFamily` is set to `true`, `net.connect` is supposed to try connecting to both IPv4 and IPv6, interleaving the address types. Instead, it appears that the array that holds the addresses in the order they should be attempted was never used after being populated.

Hey @indutny @ShogunPanda, I believe the introduced test for #48258 is covered by this, https://github.com/nodejs/node/pull/48275/files#diff-c97855fe951a3d9c4319418be09b97f6c2700565dbc65c47adfb3f520e8759e6R175 right? |

@juanarbol Nope, it's not. That test only included those addresses already in order, so there was no verification the attempt order was correct. In #48258 a test has been specifically included to verify the behavior. |

I don't think CI will be happy until the windows issue is solved; most jobs fail at this point. I prefer to wait for a bit more to kick a CI again. Or feel free to retry if needed. |
