In principle, one NetSkateKoban sensor is required for each network segment.
If multiple IP subnets exist within a single network segment, the number of NetSkateKoban sensors required will match the number of IP subnets. However, it is possible for one NetSkateKoban sensor to monitor multiple network segments.
With a multi‑VLAN NetSkateKoban sensor, a single sensor can monitor multiple VLAN networks.
