Subnetting Networks (CASE)
Case Assignment
You are required to review the case materials and conduct your own research (at least three additional sources of materials. Please be sure to use appropriate citations for materials that you collect on your own), in your own words, please write a 2- to 3-page paper (excluding the cover page and reference page) to why subnetting is necessary and what happens if we do not subnet a network.
Subnetting**A subnetwork, or subnet, is a logically visible subdivision of an IP network. The practice of dividing a network into two or more networks is called subnetting. All computers that belong to a subnet are addressed with a common, identical, most-significant bit-group in their IP address. This results in the logical division of an IP address into two fields, a network or routing prefix and the rest field or host identifier.
Why We Need Subnets**To understand why we need subnets (short for subnetwork), let’s start right from the beginning and recognize that we need to talk to “things” on networks. Users need to talk to printers, email programs need to talk to servers, and each of these “things” needs to have some sort of address. This is no different from a house address, but with one minor exception: the addresses need to be in numerical form. It is not possible to have a device on a network that has alphabetical characters in its address like “23rd Street.” Its name can be alphanumeric – and we could translate that name to a numeric address – but the address itself must be numbers alone.
These numbers are called IP addresses, and they have the important function of figuring out not only the address of “things,” but how communication can occur between them. It is not enough to just have an address. It is necessary to figure out how a message can be sent from one address to another.
