Advanced Network Mapper (ANM) is a Python 3-based utility that performs fast and efficient subnet scanning using nmap, and generates both JSON and HTML formatted reports of open ports and detected services.

This tool is ideal for system administrators, cybersecurity professionals, and penetration testers looking to quickly assess the state of hosts on a network.

FEATURES

~ Parses nmap XML output directly

~ Outputs JSON report for machine-readable integration

~ Generates clean and styled HTML reports

~ Fast scanning with multithreaded Nmap (-T4)

~ Works with any /subnet format (e.g., /24, /16)

~ No database or external service dependencies

HOW TO RUN THE SCRIPT

python -m venv /path/to/new/virtual/environment #Create a venv Environment
Source /path/to/new/virtual/environment/bin/activate # Activate venv
apt install nmap # nmap
pip3 install jinja2 # Jinja
chmod +x ANM.py # permission
./ANM.py # Run the script
 

CONFIGURE THE SCRIPT

Before running the script, you'll need to update a few variables at the top of the file to match your network environment and scanning needs.

Open the Python script (ANM.py) in your favorite text editor and locate the following section near the top:

SETTINGS subnet = "your IP Here/subnet" # example: 192.168.0.0/24

common_ports = "22,80,443,3306,8080,8443" # Ports

output_json = "scan_report.json"

output_html = "scan_report.html"

Avoid wide scans in production environments unless you know the risks.

Unauthorized use of this script against systems you do not own or have explicit consent to test is illegal and unethical.
