How do I create 4 subnets from the default 172.16.0.0/16 network (I need to use the entire 172.16.0.0/16 block)? I'm honestly not good at math and this looks very confusing to me. Is there anyone who could just explain this to me step by step? Thanx.

I'm not sure I would say /16 is a "default" :) Usually /24 is the most common.

Here is a link to a CIDR calaculator

A /16 is the same thing as a 0.0.255.255. This will give you over 65,000 subnets.

This closest number that can be divided by 4 is 64. 64 divided by 4 = 16.
So you need 16,000 (16,384) hosts per subnet?
