I've been going over my notes for subnetting, and realised I don't really understand it. Have read this fantastic question which cleared up a lot: How does IPv4 Subnetting Work?How does IPv4 Subnetting Work?
However, I'm still stuck. Takes this scenario for example:
Assume you work for medium sized law firm that has decided to install a computer network to increase the efficient distribution of its legal records. After talking to the leading partner you determine that you need at least 5 subnets for your network. The Internet Authority has assigned an address of 195.3.2.0/24 to the network of your firm.
How do I determine how many bits I need to borrow from the host to create my subnet structure? How do I get my subnet mask?
