thanks webc, but i have some questions:
I understood all that, but now I have some questions:
In the first example
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...
can u give an example of the whole 32 bit ip address and subnet for each of the 8 subnets?
I just want an example of how they look, to see if my calculations were correct...
thanks for the info WebCarnage, this could be of real help in my work.

ok following your first exampl..another question
if u want to have 8 subnets, you see that it would take 4 bits to make 8 in binary, so to get 8 subnets u would have 255.255.255.240...
but then again, to make 14 in binary it takes 4 bits....to make 10 or even 9 it takes 4 bits...so the 255.255.255.240 can be used to make 8 subnets or 14 subnets or 10 or 9?
clarify please!!!

Nooooo.... Not subnetting!!!!! Ahhh.... I can feel my brain cells dying already.
I remember having this in class, and wanting to kill myself afterwards. Thanks for the tutorial though. I'm going to save it for future reference. It's a lot better than the one in my class book.

4 bits, subnet mask 255.255.255.240, 14 subnets, 14 hosts, net*hosts= 196
CIDR /28
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
