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.

The subnet mask for the mentioned IP address is 255.255.254.0 then option 1 is also correct right.

Why subnet mask can't take as 255.255.254.0 in option A?

Why is option 1 not correct, is it true to say that a subnet address is the same as a subnet mask?
According to me, it is option 2 and 4.
Anyone, please explain in detail.

I didn't get the proper explanation.
So, please explain to me properly. (10.16.0.1 - 10.16.0.254) is this the correct range?

IP address converted to binary (128 64 32 16 8 4 2 1):
10.16.3.65 is 00001010-00010000-00000011-01000001
Subnet /23 is 11111111-11111111-11111110-00000000.
Network id: 00001010-00001000-00000010-00000000 (10.16.2.0).
Broadcastid: 00001010-00001000-00000011-11111111 (10.16.3.255).
Therefore host address range: 10.16.2.1 to 10.16.3.254.
10.16.3.65 is 00001010-00010000-00000011-01000001
Subnet /23 is 11111111-11111111-11111110-00000000.
Network id: 00001010-00001000-00000010-00000000 (10.16.2.0).
Broadcastid: 00001010-00001000-00000011-11111111 (10.16.3.255).
Therefore host address range: 10.16.2.1 to 10.16.3.254.
