Open Port Checker
Discover what ports are open and which can be safely closed
Discover the status of ports on your network with a combination open port checker and scanner
Knowing what ports are open in your network is important for your cybersecurity and for helping your network operate smoothly. With SolarWinds® Engineer’s Toolset™ (ETS), you can use the included open port checker (open port scanner) to scan your network to see the status of all the ports in your system.
You can also see which ports can be closed safely and which need to remain open, so necessary applications and services can connect to your network.
Perform full network port reconnaissance
While regular, stand-alone open port checkers can give you a sense of your network perimeter, it can be difficult to get a complete picture from this tool alone. With SolarWinds Engineer’s Toolset, you can more easily conduct comprehensive investigations of your network to find specific security risks and troubleshoot network issues.
Using ETS open port scanner and IP network browser, you can more easily sweep IP ranges to identify devices, and UDP and TCP services, to better understand what’s connected to and available on your network.
Understand how your network is configured for better troubleshooting
In addition to helping you discover open ports, SolarWinds Engineer’s Toolset comes with several tools designed to help you better understand whether your network is configured properly.
With the SNMP MIB browser, you can query SNMP-managed devices to view configurations and other MIB attributes. You can then use the assorted config tools included in ETS to manage configurations for switches and network routers.

Do you find yourself asking…
An open port allows packets sharing the same port number to travel in and out of your local area network. This is important because your hardware is constantly managing multiple tasks and activities at the same time, many of which require network access. This can pose a problem because devices typically only have one network interface. Luckily, with functioning ports, this doesn’t have to be a concern. Ports allow multiple activities and processes to access a shared network interface, meaning they can all occur simultaneously.
