I work for this company where i self progress by doing online courses through SCTE. Well I am on subnetting and I can’t wrap my head around it.

Here’s an example.

You are given an IP of 195.16.45.0 /24 and you need to divide it into 4 subnets. Answer the following questions:

How many networks or hosts are needed on each network?

How many bits do you need to borrow?

What is the delta?

Write down the network ranges.

Write down the host ranges.

I’m the kind of person that actually wants to learn something and not just pass a test for a raise. Can anyone refer me to something that can help me with this stuff?
