How to calculate a subnet mask from an IP address step by step

Diving into the world of the internet is synonymous with constantly nourishing yourself with knowledge that you never thought you could acquire. That is why, for all those interested in knowing more about the elements that make up a network, and how to calculate a subnet mask for an IP address.

Despite the normality with which you use it every day, the internet is a little more complex and deep. It keeps a series of really interesting elements and information that will help you understand how the different devices that you use every day to establish a connection to the network and surf the internet can be identified .

IP addresses

Among all the elements that surround a network, one of the most important, without a doubt, is the IP addresses. These elements are intended to identify each and every one of the devices that have established a connection to a network.

IP addresses

However, in those cases in which there are many connected devices, IP addresses are not enough to effectively identify a device, because these addresses can have practically imperceptible similarities, creating confusion

The subnet mask

Faced with the sea of ​​similar and at the same time different addresses, isn’t there a much more practical and effective way to identify one or more devices connected to the same network? Yes, that is where the subnet mask appears.

This element derives from the IP address , in fact, it is considered as another type of IP. Through it, differences can be established and the device identification process simplified.

How does it work?

The subnet mask takes the fixed parts of an IP address, and represents them by means of the number 255, while its variable part can be represented by a 0 or by any other digit.

So, an IP address, which usually consists of:, would have a subnet mask structured as follows:, as you can see, the last digit of both the IP address as well as the subnet mask, simplifying the way devices are identified.

Know your subnet mask

Do you want to know the subnet mask that your computer has? For Windows users, it is extremely easy to access this type of information. You simply have to access the command prompt and enter the command ipconfing / all, and once you press the “Enter” key, all the information will be displayed in the window.

Calculate the subnet mask of an IP address

Now, the subnet mask is a really fundamental element for all those people who must perform network administration tasks. Subnetting is vital for assigning high IP address ranges.

Calculate the subnet mask of an IP address

This procedure can be quite tedious if done manually, since you will need to remember and follow some principles and formulas that will allow you to achieve this goal.

Calculation alternatives

If you are just beginning to carry out these types of operations, which at first may seem like mathematical activities with considerable levels of complexity, because you cannot find a solution.

Fortunately for you, as well as many, many other people, certain developers have thought of these kinds of uncomfortable and exasperating situations. Making available to a large community of people, web platforms with subnet mask calculator tools.

Calculator-networks, one of the best
