Subnet Calculator with Streamlit

This repository contains a simple Streamlit-based application for subnet calculation, supporting both Fixed-Length Subnet Masking (FLSM) and Variable-Length Subnet Masking (VLSM). The application allows users to input an IP address and subnet requirements to calculate subnets based on their needs.

Features

• FLSM (Fixed-Length Subnet Masking): Enter the number of subnets required, and the app will calculate and display the subnets.
• VLSM (Variable-Length Subnet Masking): Enter the number of hosts required per subnet, and the app will calculate the most efficient subnets, sorted from largest to smallest.

Setup and Installation

Prerequisites

Ensure you have the following installed:

• Python 3.7+
• pip

Step-by-Step Guide

1. Clone the repository:

   git clone https://github.com/your-username/subnet-calculator.git
   cd subnet-calculator

2. Create a virtual environment (optional but recommended):

   python -m venv venv
   source venv/bin/activate  # On Windows, use `venv\Scripts\activate`

   Note: Make sure to create the virtual environment on the command prompt terminal and not powershell.

3. Install dependencies:

   pip install -r requirements.txt

4. Run the application:

   streamlit run Homepage.py

   This will launch the application in your default web browser. You can access it at http://localhost:8501/.

Usage

1. FLSM (Fixed-Length Subnet Masking):

   • Enter an IP address and select the CIDR.
   • Specify the number of subnets required.
   • Click on "Calculate FLSM Subnets" to view the results.

2. VLSM (Variable-Length Subnet Masking):

   • Enter an IP address and select the CIDR.
   • Specify the number of hosts required per subnet, separated by commas or spaces.
   • Click on "Calculate VLSM Subnets" to view the results.

Modifying the Code

Folder Structure

• Homepage.py: The main Streamlit app script that provides the user interface and handles user input.
• Subnet-Calculator.py: A Streamlit page that provides the user with the subnetting calculator.
• subnet_calculator.py: Contains the core functions for calculating subnets using FLSM and VLSM.
• Subnet-Chatbot.py: A Streamlit page that provides the user with a ChatGPT like UI where they can interact with the AI to learn about subnetting.

Adding New Features

1. Modify subnet_calculator.py:

   • Add new calculation logic or enhance existing functions.

2. Update Homepage.py:

   • Adjust the Streamlit UI to accommodate any changes to the calculation logic.
   • Ensure that new input fields or options are correctly handled and passed to the calculation functions.

3. Test Your Changes:

   • Run the application using streamlit run Homepage.py to verify your changes.
