Dripping

Dripping is a lightweight IP monitor written in Go that tracks your public IP address and sends Discord notifications when it changes. It compares the current IP (fetched from ifconfig.co) with the expected IP specified in a JSON configuration file.

Features

• Fetches current IP from ifconfig.co
• Compares fetched IP with the expected IP from config.json
• Sends Discord notifications when the IP changes or returns to the expected state
• Checks your IP every 5 minutes
• Persists state in a JSON file for consistency across restarts

Configuration

Configure Dripping with a JSON file (config.json):

Parameter	Type	Description	Example
expected_ip	String	Your expected network IP address	"203.0.113.1"
discord_webhook_url	String	Discord webhook URL for notifications	"https://discord.com/api/webhooks/your_webhook_id/your_webhook_token"
check_interval	Integer	IP check frequency (minutes)	5
change_message	String	Alert when IP changes (use %s for IP and timestamp)	"Warning: IP changed! Current IP: %s at %s"
restore_message	String	Alert when IP returns to expected (use %s for IP and timestamp)	"Info: IP returned to expected state (%s) at %s"

Example configuration:

{
  "expected_ip": "203.0.113.1",
  "discord_webhook_url": "https://discord.com/api/webhooks/your_webhook_id/your_webhook_token",
  "check_interval": 5,
  "change_message": "Warning: IP changed! Current IP: %s at %s",
  "restore_message": "Info: IP returned to expected state (%s) at %s"
}
