There's also the arp (8) command: you can query and manipulate the ARP table (arp stands for "address resolution protocol", which is tasked with keeping this MAC -- IP mapping up to date). For example, just typing "sudo arp" will show you a list of known IP Address to MAC address mappings. With "arp -s <ip> <mac>" you can set one such mappings. And so on.
