TOPIC: Subnetting with Class A or B

Subnetting with Class A or B 11 years 9 months ago #21504

How come in my Network+ books and just about every other web page discussing subnetting they never use Class A and B ranges?
It seem slike it would be more complicate to do those.
I mea you have 3 or 2 more places to consider. Anyone have any good links to teach this?

I also have trouble finding ranges. I can tell you how many networks and how many host per. (2 to the blah power - 2 and so on) But when it asks the ranges I get turned around! Hard to explain, I freeze. I'm writing my test the 14th and I came across this site which I find is really filled with alot of good material, like,, and

Thanks everyone

Like say you have a class A ( use with a subnet mask of .. How do you figure out the network ranges? Like to for example.. I get confused on the Class A and B. I guess b/c you're dealing with larger networks.
