You notice that a device with a manual IP address cannot communicate with other devices on the network. The network has the address 192.168.4.x with a subnet mask of 255.255.255.0. The IP address of the non-communicative station is 192.168.4.12/26. What is the most likely reason this system cannot communicate?
A)It has the wrong subnet mask
B)It is using a private IP address
C)Its IP address is wrong
D)The TCP/IP stack is corrupt

Question

Quizplus · Accepted Answer

The subnet mask is wrong, and the device will not be able to communicate with the rest of the network.
Key Takeaway: The subnet mask lets us know what part of the address refers to the network ID. In this case, the malfunctioning computer is using an additional two bits to reference the network ID. Therefore, even though the IP address looks right, this machine is logically on a different network due to it using the wrong subnet mask.
