I need a simple but reliable DHCP server with multiple ports, that assigns a port-specific IP-address to clients. It will be used in an industrial setup, where there are multiple rooms with some devices, and we need to be able to access the devices by room=ip-address (please don't ask why!)
Therefore, when the device is connected to the network plug in the room, it must get an ip-address that is specific for that room.
What kind of device can provide this, and how? It should not cost too much, but it must be very reliable.
