Limitation of Connected Devices on Ethernet Network
Is there any limitation for connecting devices on a Ethernet network?

Is there any limitation for connecting devices on a Ethernet network? I know that a controller has limitation for connecting devices, but i was told that even a network has limitations for connecting the devices. Is that true? If yes, then what is the limitation for connecting devices on an Ethernet network?

the limit is the number of addresses available on that network. You can use a subnet mask to change the number of available addresses.
