# Subnet Calculator
A simple command-line subnet calculator written in Rust.
## What it does
- Calculates subnet info based on a network address, CIDR, and number of hosts
- Handles multiple subnets
- Lets you input data manually or import from a CSV file
- Can save results as CSV or Markdown
## Getting Started
1. Make sure you have Rust installed. If not, grab it from [https://www.rust-lang.org/](https://www.rust-lang.org/).
2. Clone this repo:
```bash
git clone https://github.com/LuMarans30/Subnetting-rust.git
```
3. Enter the directory:
```bash
cd Subnetting-rust
```
4. Build it:
```bash
cargo build --release
```
5. Run it:
```bash
./target/release/subnetting
```
Alternatively, [precompiled binaries for most platforms](https://github.com/LuMarans30/Subnetting-rust/releases/latest) are available.
## Usage
### Manual Input
1. Choose option 1
2. Type in your network address with CIDR (like 192.168.1.0/24)
3. Enter how many subnets you want
4. For each subnet, enter the number of hosts you need
### CSV Import
1. Choose option 2
2. Enter the path to your CSV file
Your CSV should look like this:
(The first line is the initial network address with CIDR, then one line per subnet with the number of hosts)
```csv
,
...
```
Alternatively, you can use a slash ('/') as a delimiter:
```csv
/
...
```
## What You'll Get
For each subnet, you'll see:
- Network address
- Subnet mask
- CIDR
- Subnet class
- Broadcast address
- Gateway
- First and last usable host addresses
- Request number of hosts
- Actual number of hosts
- How many IP addresses are wasted
You can save all this info to a CSV or Markdown file if you want.
