Where and how can I see my networks Subnet Mask?

To do this first open your “command line promote” (in Windows 7 you can open a command line by going to start button and write “cmd” and in XP or earlier go to start button and click run and write “cmd”). After the command line promote window come type “ipconfig” and press enter.
Now you will see information about your IP configuration. So you will find your subnet mask at the below it is something like code for example there may be 255.255.240.0 or something like that. It is not case sensitive so you can also type “IPCONFIG”. Remember to give it without “”.
Thank you.

First of all you need to know what operating system you are using so that we would know how we can check your subnet mask.
IF YOU ARE USING WINDOWS:
To know what your Operating System (if you are using Windows) is, you can right click on MY COMPUTER on your desktop. The desktop is the first screen that you see when your computer turns on and where your icons can be seen. My Computer is usually situated on the upper left portion of your desktop. After right clicking, it will show a drop down menu, please click on PROPERTIES. Then it will open a new small window. By default, it will be on the general tab and that's where you could actually see the version of the operating system that you are using. You will either see, Windows XP, Windows Vista or Windows 7 which is under system. Once you know your operating system already, close the open window by hitting on the red x on the upper right portion and we can now go ahead and check your subnet mask.
HOW TO CHECK SUBNET MASK:
First please click on Windows icon, that's on the lower left portion of your computer screen. Then you click on RUN. It will open you a small window. Please type "cmd" without the "" then hit on ok. After that it will open another window, a black screen which is now the command prompt. Just type "ipconfig" without the"" then hit on enter. It will show you now a list of items. Look for the connection that you are using then under it you will see the subnet mask.
First please click on Windows icon, that's on the lower left portion of your computer screen. Then you click on ALL PROGRAMS.

Just type "ipconfig" without the"" then hit on enter. It will show you now a list of items. Look for the connection that you are using then under it you will see the subnet mask.
Hope this helps you! 🙂
