I like this tool because it’s updated often, runs on Windows 10 and has a 32-bit and 64-bit version. Let’s start off with a free tool for Windows PCs called SoftPerfect Network Scanner. If you never connect to your computer remotely, then having remote desktop enabled is just a security risk. When looking at open ports for a computer or device, you can easily see whether remote desktop is enabled, whether an FTP or HTTP server is running and whether file sharing is enabled or not. Anyone who connects to your network via cable or wireless could then easily search for shared folders and copy that data to their computer. For example, you may find folders that are being shared on your network by accident. Here you can see a device with hostname MSRTK has IP address 192.168.1.8.Though it’s a bit technical, the information can help you make your network more secure. Nmap done: 256 IP addresses (4 hosts up) scanned in 2.41 seconds Nmap scan report for ubuntu (192.168.1.5) Nmap scan report for hpprinter (192.168.1.2) For each device that responds to the ping, the output shows the hostname and IP address like so: Starting Nmap 6.40 ( ) at 12:46 GMT Ping scan just pings all the IP addresses to see if they respond. Now use the nmap command with the -sn flag (ping scan) on the whole subnet range. Now you have the IP address of your computer, you will scan the whole subnet for other devices. On Windows, go to the Control Panel, then under Network and Sharing Center, click View network connections, select your active network connection and click View status of this connection to view the IP address.

On macOS, go to System Preferences then Network and select your active network connection to view the IP address.

On Linux, type hostname -I into a terminal window.

First find your own IP address, in other words the one of the computer you’re using to find your MSRTK Moduls IP-address: To use nmap to scan the devices on your network, you need to know the subnet you are connected to.

To install on macOS or Windows, see the download page.

To install on Linux, install the nmap package e.g.

The nmap command (Network Mapper) is a free and open-source tool for network discovery, available for Linux, macOS, and Windows.
