My modem is plugged into an Ethernet switch. The Ethernet card in my computer and my printer are each plugged into the switch. My modem has the address internally of 10.1.1. My printer's usually 10.1.1.2. My computer's usually 10.1.1.3. However, recently on a number of occasions, I've discovered my printer or computer has a different address. No doubt, some command will tell me the current addresses of things plugged into the switch, but I don't know which. Could someone enlighten me as to the command? Also, is there some way to force my printer and computer to keep their usual addresses permanently? Otherwise, when I discover that my printer isn't working or that my firewall's blocking connections, I have to change the relevant settings temporarily to match the different numbers, which is annoying.
