IP Address Change Notifier

==========================

This script is designed to monitor and notify when the public IP address of a device changes. It uses various notification methods, including email, Telegram, and Nextcloud Talk.

Configuration

The script relies on a configuration file named config.ini to store settings. The file should be in the same directory as the script.

General Settings

• check_interval: The interval in seconds between IP checks (default: 300)
• notify_methods: A comma-separated list of notification methods (default: email)
• last_ip_file: The file to store the last known IP address (default: last_ip.txt)

Email Settings

• from: The sender's email address
• to: The recipient's email address
• server: The SMTP server address
• port: The SMTP server port (default: 465)
• user: The SMTP username

Telegram Settings

How it Works

The script supports the following notification methods:

• Email: Sends an email using the specified SMTP server and credentials.
• Telegram: Sends a message using the Telegram bot token and chat ID.
• Nextcloud Talk: Sends a message using the Nextcloud URL, token, and room ID.
