Which address does a host have to find out in order to send a data packet to another host (whose IP address they know!) If the person is on the same network? When the person is on a different network?

1. Ethernet network address

2. native address, and the router

Explanation:

Each PC is connected to the Ethernet network through the Ethernet NIC or the network interface card. And anybody from the same network can send the data packet to this host through the Ethernet network address. And when the PCs are not on the same network then they are connected through the router and are being identified through their native addresses.
