Question

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.)

Answer 1

The first thing the host does is to look for the MAC address of the default router(gateway).

Step-by-step 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.

Hope this helps!
