Overview

IP Range Scanner is a powerful Python tool designed to scan ranges of IP addresses for web servers and collect their HTML titles. It supports concurrent scanning, multiple protocols (HTTP/HTTPS), custom port configurations, and provides comprehensive logging and CSV export capabilities.

Features

• Concurrent Scanning: Utilizes multi-threading for efficient scanning of large IP ranges
• Protocol Support: Handles both HTTP and HTTPS protocols
• Flexible Input: Supports both command-line arguments and interactive input
• Comprehensive Logging: Detailed logging with both file and console output
• Data Export: Automatic CSV export of scan results
• Input Validation: Robust IP address and range validation
• Configurable Settings: Customizable timeout, worker threads, and ports
• Error Handling: Comprehensive error handling and graceful exits

Requirements

• Python 3.7+
• Required packages:

  requests>=2.26.0
  beautifulsoup4>=4.9.3
  

Installation

1. Clone the repository:

   git clone https://github.com/9de/IP-Range-Web-Title-Checker.git
   cd ip-scanner

2. Create and activate a virtual environment (recommended):

   python -m venv venv
   source venv/bin/activate  # On Windows: venv\Scripts\activate

3. Install required packages:

   pip install -r requirements.txt

Usage

Command Line Interface

python ip_scanner.py --start-ip START_IP --end-ip END_IP [OPTIONS]

Interactive Mode

Simply run:

python ip_scanner.py

Configuration Options

Option	Description	Default
--start-ip	Starting IP address	Required
--end-ip	Ending IP address	Required
--ports	Ports to scan (space-separated)	80 443
--timeout	Request timeout in seconds	5
--workers	Number of concurrent workers	10
--output	Output CSV filename	scan_results_[timestamp].csv

Output

Log Files

• Location: scan_[timestamp].log
• Format: YYYY-MM-DD HH:MM:SS - LEVEL - MESSAGE

CSV Export

• Location: scan_results_[timestamp].csv
• Columns:
  • IP Address
  • URL
  • HTML Title

Examples

1. Basic scan with default options:

   python ip_scanner.py --start-ip 192.168.1.1 --end-ip 192.168.1.255

2. Custom port scan:

   python ip_scanner.py --start-ip 10.0.0.1 --end-ip 10.0.0.100 --ports 80 8080 8443

3. Adjusted performance settings:

   python ip_scanner.py --start-ip 172.16.0.1 --end-ip 172.16.255.255 --timeout 3 --workers 20

Security Considerations

1. Network Policies: Ensure compliance with network policies before scanning
2. Rate Limiting: Be aware of potential rate limiting on target networks
3. Legal Implications: Obtain necessary permissions before scanning non-owned networks
4. SSL Verification: Default SSL verification is enabled for security

Troubleshooting

Common Issues

1. Connection Timeouts

   • Increase timeout value using --timeout
   • Reduce number of workers using --workers

2. Memory Issues

   • Reduce the IP range size
   • Decrease number of concurrent workers

3. Permission Errors

   • Ensure write permissions for log and CSV files
   • Run with appropriate privileges

Debug Mode

Set environment variable for detailed logging:

export IP_SCANNER_DEBUG=1  # On Windows: set IP_SCANNER_DEBUG=1

Class Structure

IPScanner

Main class handling the scanning operations.

class IPScanner:
    def __init__(self, timeout: int = 5, max_workers: int = 10)
    def setup_logging(self)
    def get_html_title(self, url: str) -> Optional[str]
    def validate_ip_range(self, start_ip: str, end_ip: str) -> bool
    def scan_ip(self, ip: str, ports: List[int]) -> List[Tuple[str, str, str]]
    def scan_ip_range(self, start_ip: str, end_ip: str, ports: List[int]) -> List[Tuple[str, str, str]]
    def save_results(self, results: List[Tuple[str, str, str]], filename: str)

Data Flow

1. User input validation
2. IP range conversion
3. Concurrent scanning
4. Result collection
5. Data export

Performance Optimization

• Thread pool for concurrent scanning
• Configurable timeout and worker count
• Efficient IP address handling
• Minimal memory footprint
