- THe problem is that when subnetting you can not assign an address to a host
- such that the subnet number is all one's or all zero's in binary.
-
- You have decided to use a subnet number of 192 which is 1100 0000 in binary.
- This would yield the following:
-
- 00 0-64
- 01 65-127
- 10 128-195
- 11 196-255
-
- Now the first and last of these choices is invalid so you have to throw
- them out. You are using the address 192.233.25.15 which is in that first
- throw out range. Shift down one range and use numbers in that range for
- one subnet and the next range for you second subnet.
