    I’m currently using WiFi but I would like to have a switch by the TV table to connect all devices (Apple TV, PS4, AVR, TV) by Ethernet to improve connection and stability.

    Now with WiFi each device has its own local IP, I can see the devices on the network, forward ports, access some web GUI etc.

    How do local IP addresses work with a switch?
    Do a need a special switch?

    IP address aren't effected by switches (unless they are layer 3 switches) because they operate at the Ethernet level, not the IP level.

    That said, if you change your client from a wireless connection to a wired connection its MAC address will change (because the client is now using a different network interface). So you will have to change any IP reservations you have made to reflect the new MAC addresses.

    Ah I understand, thank you. That makes life much easier.
    For some reason I was wrongly under the impression that each ethernet port gives one local IP.
