This is a profile of the projects I've created.
In studying for the CCNA certification as a part of my bachelor at university, was learning how to perform variable length subnet masking (VLSM). It's a method of subnetting a network of varying sizes.
With the desire to create an online solution that might be helpful for other students, I created a page on this website which offers an quick and easy way to calculate VLSM. It's essentially an online version of the free and open source command line tool ipcalc made by Krischan Jodies.
You can see it live at vlsm(1). The source code can also be viewed here.
