💭 Motivation

This program was developed to help cadets from École 42 on studying for and taking the netwhat test. For further information about this, please refer to the netwhat repo.

🛠️ Usage

Requirements

The program is written in C language and thus needs the gcc compiler and some standard C libraries to run.

Installation

Simply clone the repository:

$ git clone https://github.com/appinha/ip_calc-netwhat-42cursus.git

Running

Go to the cloned directory:

$ cd ip_calc-netwhat-42cursus

For information about the given IP address, run:

$ sh ipc.sh [IP address] [subnet mask or CIDR]

For information about the given subnet mask/CIDR, run:

$ sh ipc.sh [subnet mask or CIDR]

💡 Tips

Set an alias for running the program, for instance:

alias ipc="cd path/to/ip_calc-netwhat-42cursus && sh ipc.sh $1 $2"

Then, it suffices to run:

ipc [IP address] [subnet mask or CIDR]

or:

ipc [subnet mask or CIDR]
