PTRack is a fast, scalable Python tool for performing reverse DNS (PTR) lookups and optional forward (A/AAAA) lookups on IP addresses listed in a CSV file. It outputs results in JSON or CSV format, optimized with threading, caching, and customizable output options—perfect for network analysis on Windows, Mac, and Linux.

• Input: Processes CSV files with IPs in the first column (header required, e.g., "IP").
• DNS Lookups: Performs reverse (PTR) and optional forward (A/AAAA) lookups using a specified DNS server.
• Output: Generates structured JSON (default) or CSV with an overview and detailed analysis, customizable via --show-invalid and --show-no-records.
• Cross-Platform: Runs seamlessly on Windows, Mac, and Linux without modification.
• Progress: Displays real-time plain text updates to stderr (e.g., "Processing IPs: 50% (2500/5000)").
• Encoding: Ensures consistent UTF-8 handling for all I/O.
• Logging: Offers configurable levels (debug, info, warning, error) with performance metrics.
• Security: Includes input validation, path sanitization, and a 1M IP limit to prevent abuse.
• Speed: Leverages threading (default: 8, max: 16) and optional caching via --cache-file for efficiency.
• Scalability: Handles 10,000+ IPs with batching (default: 2000 IPs per batch).

• Python 3.9+: Required for compatibility with dnspython.
• Poetry: Package manager for easy dependency management and installation.

1. Clone the Repository:

   git clone https://github.com/jtjones1028/ptrack.git
   cd ptrack
   

2. Install with Poetry:

   poetry install
   

3. Verify Installation:

   poetry run ptrack --version
   

PTRack is a command-line tool designed for simplicity and flexibility. Here’s a step-by-step guide to using it effectively:

1. Prepare Your CSV File:

   • Create a CSV with a header (e.g., "IP") in the first column, followed by IP addresses (e.g., 8.8.8.8, 192.168.0.1).
   • Example (ips.csv):

     IP
     8.8.8.8
     192.168.0.1
     invalid_ip
     

2. Run the Tool:

   • Basic command:

     poetry run ptrack ips.csv 8.8.8.8

   • Add options for customization (see Common Options below).

3. Interpret the Output:

   • JSON (default): Check "overview" for stats and "analysis" for successful lookups (configurable with --show-invalid and --show-no-records).
   • CSV: Open in a spreadsheet for tabular data with comments summarizing stats.

4. Leverage Caching:

   • Use --cache-file=cache.json to save results and speed up future runs on the same IPs.

5. Monitor Progress:

   • Watch stderr for updates (e.g., "Processing IPs: 50% (2500/5000)").
   • Enable --log-level=info for detailed timing and cache usage logs.

• Detailed Logs: --log-level=info (e.g., [INFO] Processing 8.8.8.8 took 0.45s).
• CSV Output: --format=csv (spreadsheet-friendly).
• Cache Results: --cache-file=cache.json (reduces runtime on repeat runs).
• Show All IPs: --show-invalid (includes invalid IPs), --show-no-records (includes IPs with no DNS records).
• Version Check: --version (displays PTRack 1.0.0).

PTRack is versatile for various network-related tasks. Here are some typical scenarios and how to apply the tool:

• Scenario: You have a list of public IPs (e.g., from a server log) and want to identify their domains.
• Command:

  poetry run ptrack public_ips.csv 8.8.8.8
