He observed that an IP address is the logical addressing scheme for nodes on a network. IP addresses exist at the Network layer of the OSI Model and help facilitate the L3 goal of “end to end” delivery. On the other hand, a MAC address is the physical addressing scheme for individual NIC cards on each node of a network. MAC addresses exist at the Data Link layer of the OSI Model and help facilitate the L2 goal of “hop to hop” delivery. But in this point, Rasel was every curious to know the depth process how this 2 logical and physical addressing correlate with each other. ...
