Local Area Networks (LANs)
Each adapter on LAN has unique LAN address. A MAC, LAN, physical or Ethernet address is used “locally” to get frame from on interface to another physically-connected interface. Usually, 48 bit MAC address burned in NIC ROM, it does not change and it is portable, eg.: 2A-2B-1F-2C-93-53. However, IP hierarchical address is no portable, it depends on IP subnet to which node is attached.
