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?
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.

I think answer should be B. Because 2nd subnet should be 128-192. I. E 128 is network address and 192 is broadcast address. Hence valid host range should be 129-191. So answer is B.

The answer is right they said "usable" ip address, so the network is 192.168.168.128 to .191, 128 is network address and 191 is broadcast address.

256-192 = 64 so increment by 64.
Networ - Broadcast
64 - 127
128 - 191 > so the usable host address range is 127 - 190 (answer is A).
192 - 255.
Networ - Broadcast
64 - 127
128 - 191 > so the usable host address range is 127 - 190 (answer is A).
192 - 255.

Why the value should be between 129 and 191. It should be between 128-191. Also why the broadcast address is 191?

128 is called a network address and 191 is called broadcast address.
Thanks it is easy to understand.

@Richa.
Where did you get that 191?
As you said n/w add starts from 128 and end to 191 how?

@Ravi Sankar.
Why you call 64 as magic number and why not 192? Please help me.
