Which of the following is the valid host range for the subnet on which the IP address 192.168.168.188 255.255.255.192 resides?
192.168.168.129-190
192.168.168.129-191
192.168.168.128-190
192.168.168.128-192
Answer: Option
Explanation:
256 - 192 = 64. 64 + 64 = 128. 128 + 64 = 192. The subnet is 128, the broadcast address is 191, and the valid host range is the numbers in between, or 129-190.

64 - 2 = 62 then b is the answer.

Hi, @All.

Subtract 192 from 256 = 64,

Means, the subnetting has been done by dividing into four parts, 64 * 4 = 256.
Now see the option.
64 * 2 = 128,
And 64 * 3 = 192.

So IP add should be in between.

192.168.168.129 to 192.168.168.191.

128 is called a network address and 191 is called broadcast address.

Thanks it is easy to understand.
