Lets say, for example, that you want 8 subnets and will be using a class C address.
You get 255.255.255.240 as the subnet mask...
so now we have 8 subnets, ok now waht about hosts? How many hosts can we have per subnet...?
4 bits, subnet mask 255.255.255.240, 14 subnets, 14 hosts, net*hosts= 196

CIDR /28

clarify please!!!
Mate, I don't understand where your comming from. If your taking about bits and bytes, then listen up.
Code:
0     0     1     0     1     1     1     0
|     |     |      |     |     |     |      |
128  64   32      16      8     4     2     1
Now, that was a simple char, with a byte - or octet - consisting of 00101110. Now we add.

0 + 0 + 32 + 8 + 4 + 2 + 0 = 46

This happens because the 0 bits arn't added, while the 1's are.

Hope it helps
