10 / 20

A company has a network that uses the 192.168.1.0/24 subnet. What is the first usable IP address in this subnet?

192.168.1.0

192.168.1.255

192.168.2.1

192.168.1.1

192.168.0.1

Correct Answer: 192.168.1.1
Explanation: The first usable IP address in the 192.168.1.0/24 network is 192.168.1.1, with 192.168.1.0 being the network address and 192.168.1.255 being the broadcast address.
