Port Monitoring


Monitor any IP address for port changes. This feed alerts you when ports open or close on the IPs you're tracking—whether it's your infrastructure, a service you depend on, or any network you need to monitor.


Monitor Any IP and Specific Ports

Enter any IP addresses you want to monitor and specify which ports matter to you. Use individual port numbers (22, 80, 443) or port ranges (20-23, 8000-8100). The number of IPs you can track depends on your plan: one IP is free, more are available with premium.


Track Port Changes in Real Time

Get instant alerts when ports open or close on any IP you're monitoring. See exactly which port changed, when it happened, and what service might be running. Track your own servers, monitor third-party services, or watch any infrastructure you need visibility into.


Flexible Monitoring Schedule

Set multiple check times throughout the day. Check every morning, again at noon, again before you leave work—whatever frequency keeps you informed. Each check respects your time zone, so notifications arrive at the right local time.
