MAC address (Media Access Control address) is a unique identifier assigned to network interfaces for communications on the physical network segment. It is a 48-bit address burned into the NIC's ROM. Tokens are used in token-based network protocols like Token Ring. IP address is a unique identifier assigned to each device on a network, but it is not burned into the NIC's ROM. Host address could refer to either the IP address or the address used to identify a specific device on a network.
