CIDR4 Example

Source https://www.youtube.com/watch?v=iDiGBIOq7ec

24.10.178.233/10


We have 10 1's from the CIDR notation

11111111.11000000.00000000.00000000

Subnet MASK
255.192.0.0

1) Find the increment
    The last 1 is 64's place, so we have  i = 64

2) Find the Network ID

24.0.0.0
24.64.0.0  --- This is way higher than 24.10
So 24.0.0.0  would be our Network ID

3) Find the First IP, we need to ADD 1 to our Network ID
So we ADD 1 to our Right Hand side
 24.0.0.1

4)  The last IP would be  24.64.0.0   minus 2
                          So 24.63.255.254
5) The Broadcast IP would be   24.63.255.255

The Next number after the broadcast ip  24.64.0.0

Which is the beginning or the Network ID of your next subnet
