I used to be pretty good with VLSM addressing, but it's been a while since I've looked at it and I'm confused. I don't have a problem subnetting an existing subnet into equal subnets, but I need some help in subnetting with variable subnets. For example, if I need five subnets with 2, 7, 29, 34, and 100 hosts, what is the best way to figure that by hand? I know I can use the calculator, but I want to understand how to do it by hand.
I have this problem too.
