If the IPv4 address of a host on a LAN is 192.

Detailed Explanation:With a /30 subnet mask, the valid IP range is 192.168.1.0 - 192.168.1.3:

192.168.1.3 is the broadcast address, so it can be a destination.

192.168.1.1 and 192.168.1.2 are host addresses.

255.255.255.255 is the limited broadcast address, which any device can use to reach all hosts on the local network.
