Raspberry is installed in a device that can be connected by wire to different routers. Therefore, DHCP is enabled on it, it receives the corresponding IP from the router. No problem, everything works.
But in the same network there is an arduino ethernet module with a static IP. How would I, in addition to receiving IP via DHCP (so that the Internet was on the raspberry) add a static IP to the same network card? In Windows, this is called alias or additional IP, done in the settings of the network adapter. Tell me how to do this in raspberry?
