Nmap stands for Network Mapper and is an open source tool for network exploration and security auditing which comes standard with Kali Linux but is also available for Windows, OSX and many other UNIX platforms.

Earlier I had written a post on on your network and mentioned a couple of smartphone apps you could use to scan your home network. The apps do a pretty good job of scanning your network automatically and giving you some details on each device. I didn’t go into much detail about the apps in that post since it was focused on catching unauthorized users on your network. In this article, I’ll talk in more detail about these two apps that can be used on Apple or Android devices and I’ll also mention desktop apps that you can run on Windows and Mac OS X. These network scanning tools allow you to not only see all the devices on your network and their IP addresses, but also view folders shares, open TCP/UDP ports, hardware MAC addresses and more. So why would you care about this information? Though it’s a bit technical, the information can help you make your network more secure. For example, you may find folders that are being shared on your network by accident. Anyone who connects to your network via cable or wireless could then easily search for shared folders and copy that data to their computer. 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. If you never connect to your computer remotely, then having is just a security risk. Windows Network Scanner Let’s start off with a free tool for Windows PCs called. I like this tool because it’s updated often, runs on Windows 10 and has a 32-bit and 64-bit version. The program also doesn’t require any installation, which means you can carry it on a USB stick or save it to Dropbox and use it on any computer you want. When you run the executable file for your version of Windows (), you might see a message saying that Windows Firewall has blocked the program. Make sure Private networks is checked and then click on Allow access. Once the program loads, you’ll need to enter your network starting and ending IP address range. If you don’t know this, don’t worry. Just click on Options, IP Address and then click on Auto Detect Local IP Range. ![]() You’ll get a popup window with the detected IP addresses for IPv4 and IPv6 on any network cards you have installed, including virtual ones. For most home users, you’re only going to see one item listed under both IPv4 and IPv6. Unless you have IPv6 setup, you should click on the network card listed under IPv4.

You’ll see the Start Scanning button at the right, which you can click to start a scan. However, you should first set the scanning options before performing a scan. Click on Options and then Program Options. On the General tab, the only option you may want to check is Always analyze device. By default, the scanning program will only show you devices that respond to certain requests, so the final list may not show all the devices that are actually on your network because some devices simply do not respond. The scan does take quite a bit longer (several minutes compared to several seconds), but it’s worth it if you really want to see every device on your network. The Additional and Workstation tabs are really only useful for corporate environments where you have many machines on the same network and you want to get information about each computer.

This will open another window that lists out some TCP port groups. You want to click on HTTP and Proxy and then press the SHIFT key and click on Database servers to select all three items. Back on the main screen, you should see all the port numbers listed in the text box. Go ahead and also check all the boxes for open UDP ports. At this point, click OK to go back to the main program screen. Now click Start Scanning and you should see results slowly added to the list. In my tests, the program was able to find 16 devices on the network when checking the Always analyze device option compared to just 11 items when not checked. Any item with a plus sign to the left of the IP address means that it has shared folders.
