Automated Fetch of Public IP Addresses via Webhook

This n8n workflow is designed to fetch and aggregate the public IP addresses of the hosting machine. It begins with a webhook that requires header authentication, allowing external systems to trigger the process securely. When triggered, the workflow repeats the IP address fetching process ten times, sending HTTP requests to ‘https://api.ipify.org’ to retrieve the current public IP. The retrieved IP addresses are collected and aggregated for further use, such as logging, monitoring, or alerting. The final step responds with a unique list of IP addresses to the webhook caller, useful for tracking IP changes or ensuring connectivity. This workflow is ideal for scenarios requiring regular validation or monitoring of your server’s public IP address, especially in dynamic IP environments or for security auditing.
