2.
Which two statements describe the IP address 10.16.3.65/23?
- The subnet address is 10.16.3.0 255.255.254.0.
- The lowest host address in the subnet is 10.16.2.1 255.255.254.0.
- The last valid host address in the subnet is 10.16.2.254 255.255.254.0.
- The broadcast address of the subnet is 10.16.3.255 255.255.254.0.
Answer: Option
Explanation:
The mask 255.255.254.0 (/23) used with a Class A address means that there are 15 subnet bits and 9 host bits. The block size in the third octet is 2 (256 - 254). So this makes the subnets in the interesting octet 0, 2, 4, 6, etc., all the way to 254. The host 10.16.3.65 is in the 2.0 subnet. The next subnet is 4.0, so the broadcast address for the 2.0 subnet is 3.255. The valid host addresses are 2.1 through 3.254.

Why it is started from 10.16.2.0? Why not from 10.16.1.0 or from 10.16.3.0 please tell.

Why option 3 is wrong?
(The last valid host address in the subnet is 10.16.2.254, 255.255.254.0).
I think option 3 is wrong because 10.16.3.254 is the last. Since in 3rd octet its 3 not 2. Therefore, The last valid host address in the subnet is 10.16.3.254.
(The last valid host address in the subnet is 10.16.2.254, 255.255.254.0).

After calculating how did we come to know that "the possible networks will be 10.16.2.1 to 10.16.3.254"?

I don't understand how this will be the right answer.

255.255.254.0 is the subnet mask for the network right?
Then why not option C is correct?
