ip2cidr 0.1.0

A tool to convert IP addresses to /24 CIDR notation

ip2cidr

A Python tool to convert IP addresses to /24 CIDR notation.

Installation

pip install ip2cidr

Usage

The tool can be used from the command line:

# Convert a single IP
ip2cidr -i "10.200.2.132"

# Convert multiple IPs (comma-separated)
ip2cidr -i "10.200.2.132,192.168.1.100,172.16.5.200"

# Use a different separator for output (default is comma)
ip2cidr -i "10.200.2.132,192.168.1.100" -s " "

Arguments

• -i, --ips: Required. Comma-separated list of IP addresses to convert
• -s, --separator: Optional. Output separator (default: comma)

Example Output

$ ip2cidr -i "10.200.2.132,192.168.1.100,172.16.5.200"
10.200.2.0/24,172.16.5.0/24,192.168.1.0/24

$ ip2cidr -i "10.200.2.132,192.168.1.100" -s " "
10.200.2.0/24 192.168.1.0/24

Python Usage

You can also use the tool in your Python code:

from ip_converter import ip_to_cidr

# Convert IPs to CIDR
ips = "10.200.2.132,192.168.1.100"
cidrs = ip_to_cidr(ips)
print(cidrs)  # ['10.200.2.0/24', '192.168.1.0/24']

Development

Running Tests

To run the tests, first install the development dependencies:

pip install -e ".[test]"

Then run the tests with pytest:

pytest

This will run all tests and generate a coverage report. The tests cover various scenarios including:

• Single IP conversion
• Multiple IP conversion
• Duplicate network handling
• Invalid IP handling
• Empty input
• Whitespace handling
• Partial IP addresses
• Special IP addresses (localhost, etc.)

Features

• Converts IP addresses to their corresponding /24 CIDR networks
• Handles multiple IP addresses
• Removes duplicates and sorts the output
• Customizable output separator
• Error handling for invalid IP addresses
• Comprehensive test suite with 100% coverage

Requirements

• Python 3.8 or higher
• argparse>=1.4.0
