   How Mac and IP address messages work?

   • As we already saw, MAC and IP address messages from a source to a destination. However, only networked entities in the same local network (or group) know the MAC address of a particular device. In such a way, a message must arrive at the destination’s network using IP. Then, it is addressed and forwarded to the final destination using MAC.
