Subnetting Tutorial For Beginners Pdf

In this example, it is the first network. Imagine a network with a total of addresses a Class C network.

The smaller networks created the smaller broadcast domains are formed hence less broadcast traffic on network boundaries. The Subnetting Concept You will be surprised how easy the concept of Subnetting really is.

Subnetting tutorial for beginners pdf

Now that we have basic subnetting figured out and know how to convert to binary, this will be a very brief section on subnet mask shorthand. There are basically three types of subnetting questions that will be asked in our practice section, on any exam, or you need to answer in real life. The Subnet mask is changed accordingly to reflect subnetting. When you are done with this tutorial, telecharger union magazine pdf these questions will be no harder than simple addition or subtraction.

This makes solving the actual question very easy. In addition, the first six bits of the third octet are also common. Do this before you even look at the first question! You should always assume the first network can be used unless you are told otherwise.

The remaining rows are a convenience to quickly determine various exponents. For this next section, I suggest you create your own cheat sheet so you do not have to scroll up to follow along. We will go over these question types and show you how to use the cheat sheet to find the answer very quickly. As our analogy stands right now, we don't know how many apartments are in your building.

In this example, the first octet is identical and so are the first five bits of the second octet. It may be easier to draw a line through all four binary numbers at the point where the bit pattern changes. Remember that each octet represents eight binary digits - Each placement of those binary digits represents a decimal number. In addition, the mastery of these concepts will give you a major advantage when you sit for the exam.

The first thing we are going to do is create a Subnet Cheat Sheet. Welcome to the subnetting. This specific program is classified in the Network category where you can find some other similar courses. Here is kind of a loose analogy that should make this very clear.

In our analogy, each set of numbers may represent a geographic area. Your mail carrier would take the letter to the post office in your town, and the post office would route the letter to the building next-door.

Now it's time to Practice Subnetting! However, chances are this will not happen on any current exam. No worries, this is going to be very easy. No matter which of the four criteria the question asks, you should always follow these identical steps. To make more subnet in Class A, bits from Host part are borrowed and the subnet mask is changed accordingly.

If the letter was being mailed to someone in your own building, the router or postal carrier switch would know that it does not have to leave the building your subnet and would send it directly. For many entry-level to intermediate computer networking exams, the need to quickly solve subnet based questions is apparent. The concept of a subnet mask, is what tells the mail carrier which addresses are within a given network. It doesn't make much difference if you have a router in your house, or a router in your business.

To further this analogy, think of a router as a post office. What happens if you want to send it to the building next-door? One of these addresses is used to identify the network address and another one is used to identify the broadcast address on the network.


This tutorial explains Subnetting step by step with examples. You can see that the total amount of addressable hosts is reduced instead subnetting tutorial for beginners but subnetting tutorial for beginners management of addressing space is gained. Fantastic course for beginners or people who are new to this domain. Therefore, we are left with addresses subnetting tutorial for beginners for addressing hosts. We get this information by converting the decimal numbers within the subnet mask to binary.

In the not too distant past, it was considered bad practice to use the first network in your subnet range. Breaking up large networks into smaller parts would be more efficient and would conserve a great amount of addresses.

It should be noted that in the past using subnet zero and all-ones subnet was not allowed. Breaking large networks into smaller ones could simplify fault troubleshooting by isolating network problems down to their specific existence.

Who share their knowledge, you can discover the extent of our being selected to easily learn without spending a fortune! The broadcast address is used for a specific type of network traffic that is destined for every device attached to a network. The router in your home is translating your private address to your public address. Practice is very important because practice makes a man perfect.
