function - IP plan

[TWE3K]

Hi, I need to make an IP plan

for explanation gives an example:

 

I have as IP 192.168.0.0

 

user completes it wants in any network guests .. I can adjust it to the nearest power of 2 and there is my example:

8,16,32,64,128,256,512,1024,2048 and so on ..

 

Now I can sort the values ​​from largest to smallest

for example: 2048,64,32

 

I have these values ​​saved in ARRAY and now I need to create a FUNCTION that will do this

The first value in the array is 2048 it means that

network address is:

192.168.0.0 - 192.168.7.255

 

the next value in the array is 64

network address is:

192.168.8.0 - 192.168.8.63

 

the next value in a field of 32

network address is:

192.168.8.64 - 192.168.8.95

 

I  need to calculate:

1. Network address

2. Broadcast

 

Anyone knows what function create this calculated? Thank you very much for any assistance.
