The scripts connect only to 127.0.0.1 and ::1, with up to four concurrent attempts and a 1.5-second timeout each. They send no application data, read no process information and require no administrator privileges.

If IPv6 is unavailable, its attempts are reported as failed with a reason. A successful connection does not reveal the listening process, protocol or public reachability.
