A fast and efficient IPv4 ping sweep tool written in Python. This utility allows you to quickly discover active hosts within a specified network range by performing concurrent ICMP echo requests (pings). It's built to be cross-platform and utilizes Python's standard library features for robust network scanning.

• Concurrent Scanning: Leverages concurrent.futures.ThreadPoolExecutor to send pings to multiple hosts simultaneously, drastically reducing scan time for large networks.
• Cross-Platform Compatibility: Automatically adapts ping command syntax for Windows, Linux, and macOS.
• CIDR Support: Accepts network ranges in standard CIDR notation (e.g., 192.168.1.0/24).
• Robust IP/Network Handling: Uses Python's built-in ipaddress module for accurate network parsing and host iteration.
• Clear Output: Provides real-time updates of reachable hosts and a summary at the end.
• Error Handling: Catches and reports invalid network inputs or issues with the ping command itself.
• Configurable: Allows setting timeout for individual pings and the number of concurrent workers.

• System ping Utility: This tool relies on your operating system's native ping command being available in your system's PATH.
• Firewalls: Host-based firewalls (e.g., Windows Firewall, ufw on Linux) or network firewalls may block ICMP traffic, leading to hosts appearing "offline" even if they are active.
• Permissions: While running ping usually doesn't require root/administrator privileges, some highly restricted environments might behave differently.

No special installation is needed beyond a standard Python 3 environment. All dependencies are part of Python's standard library.

Simply download the ping_sweep.py file and place it in your desired project directory.
