Similar (but different) question: Assign an IP address based on switch port
I regularly need to test our hardware products. Usually that consists of having ~50 devices sitting on a bench for some time from 1 day to 14 days. Often we have a wifi connection to the device, so we use this comms channel to manage testing. Each time I do this testing I have to do some kind of bringup (e.g. onboarding onto the wifi network) to be able to talk to each device and manage the testing. This can be cumbersome and time consuming.
Would a router allow me to set the host IP on each port to a pre-determined IP? This would allow me to plug a device into a port and know how to address it without any additional bringup.
I know that switches have a lot more functionality than they used to - is a switch potentially a cheaper option?
