Subnetting

Hello everyone, my question is how do you do a subnet like this.
192.168.2.1
255.255.255.0

What i did was 256-255 = 1. Since it is a Class C. Block Size =1.
0.0,1.0,2.0,3.0,4.0,5.0.
0.1
0.254
0.255
Interesting Octet is in the 3rd?
so for the first subnet 192.168.0.0. the first valid host would be 192.168.0.1?

In the book it says 192.168.2.0

you know it is a class c. but the block size is 256
the subnet is 255.255.255.0 So the first 3 octets stay the same. 192.168.2.0 is the network.
192.168.2.1 is the first host
192.168.2.254 is the last host
192.168.2.255 is the broadcast address
the interesting octet is the fourth the interesting octet is the first one from the left that is less than 255

The interesting octet will always be the first octet moving from left to right, that has at least 1 host bit in it.
