IPWatcher is a simple Python script that tracks your public IP address and logs it into a CSV file whenever it changes. It does not require any API registration, and it will monitor and log your connection's identity with timestamps for future reference.

• Tracks public IP address changes.
• Logs IP address with timestamps in a CSV file.
• No API registration required.
• Supports searching logs by date or IP address.
• Logs ASN (Autonomous System Number) and associated information for the IP.

To use IPWatcher, follow the instructions below.

• Python 3.x installed on your machine.
• Required Python libraries: requests.

You can install the required dependencies using pip:

pip install requests

Run the script to log your public IP address:

python3 IPWatcher.py

To search for logs of IP addresses on a specific date:

python3 IPWatcher.py --search-date YYYY-MM-DD

To search for all logs that contain a specific IP address:

python3 IPWatcher.py --search-ip YOUR_IP_ADDRESS

You can set up a cron job to run the script automatically every 2 minutes (or any other interval).

1. Open your crontab file by typing the following command in your terminal:

crontab -e

2. Add the following line to run the script every 2 minutes:

*/2 * * * * /usr/bin/python3 /path/to/your/IPWatcher.py

Make sure to replace /path/to/your/IPWatcher.py with the full path to the IPWatcher.py script on your system.

The script will now run every 2 minutes and will log the IP address if it changes.

The log file will be saved with the name ip_log_YYYY.csv where YYYY is the current year. Each entry contains:

• Start Date (timestamp of the IP change).
• End Date (timestamp when the IP was replaced or a new one was assigned).
• Public IP Address.
• ASN (Autonomous System Number) and associated network details.

Example log entry:

Start Date, End Date, IP Address, ASN
2025-04-15 12:45:00, 2025-04-20 18:00:00, 198.51.100.100, AS64501 ExampleNet-2
