What is the first thing a host does when attempting to communicate with a remote device (not on the same subnet)? (Note: Assume that communication is via IP address.)
The first thing the host does is to look for the MAC address of the default router(gateway).
Explanation:
The network address and the MAC address play very crucial roles when there is a need to send packets from one network to another i.e across different networks since every device knows, at least, the IP address of it's default gateway.
