Description

This test would require a test helper that listens on all ports which we intend to measure for filtering.

The probe would then attempt to connect to every port on this target host and discover if it's able to establish a connection.

I think this would be very useful to uncover basic forms of censorship that just rely on simpler port filtering. It would also have the side-effect of being able to discover if some ports are reachable during an internet outage event (see for example open ports in KZ during the blocking event of 2022: https://ntc.party/t/network-shutdown-all-around-kazakhstan/1601/20).
