Using network discovery to map the ports on your network can help ensure unnecessary ports are kept closed to prevent access by an intruder. If a device has open ports that aren’t necessary for the device to be used, this could be a security issue. Network discovery determines which ports are in use, and which ports are open on each device. The importance of discovering this part of the network is twofold: it helps you to ensure, first, every allocated IP address is valid and isn’t being used by a malicious or rogue device and second, your network is set up in the most efficient way, by not leaving abandoned IP addresses or subnets to be used for other purposes. The first aspect of network discovery is finding all the IP addresses on the network, including static, dynamic, reserved, and abandoned IP addresses capable of being reallocated. How to Choose the Best Network Discovery Tool What Is Network Discovery? I also review my favorite discovery solution on the market today- SolarWinds ® Network Performance Monitor, and explain why its capability to automatically discover and map your network, showing you network connections and topology with the easy-to-read NetPath ™ tool, sets this network discovery tool apart from the rest. To understand this problem a little more, I’ll explain what network discovery is and why it matters, and then I’ll go through the best network discovery tools currently on the market capable of helping you keep track of your network devices. This becomes increasingly important if you use combinations of virtual networks, cloud servers, and both wired and wireless networks, as the hybrid network topology can become seriously complex. The solution to this issue is using a network discovery tool to ensure your network structure is always documented. In some cases, your network can grow so quickly you may have trouble keeping up. This free Wi-Fi app is for Windows, Linux, and Mac computers.While we might like to think our networks are perfectly maintained and documented, the reality is sometimes we lose track. You can copy all the details of any device to the clipboard as well as export some or all of the results to a TXT, CSV, XML, or LST file. In addition to identifying a device's IP, ping response, hostname, and open ports, the settings in Angry IP Scanner let you toggle on other fetchers to see details like NetBIOS info, the MAC address, and the MAC vendor.Īdvanced settings let you change the ping method and timeout, define which ports should be scanned, and eliminate all devices from the results list that either doesn't respond to a ping or have no open ports. It even automatically determines which addresses to scan based on the default gateway's address. This program is useful if you need to find every device connected to your network, as you make a scan between any two IP addresses. It's portable so it can run from a flash drive or other temporary location. ![]() IPhone, iPad, and Android users can install Network Analyzer Lite.Īngry IP Scanner is another free Wi-Fi app that simplifies network scanning. You can download Network Analyzer Pro for iOS or Network Analyzer Pro for Android. Network Analyzer Pro is the non-free version of this Wi-Fi app that removes the ads and includes other features like a speed test and port scanner. Network Analyzer Lite also has a LAN tool that scans the Wi-Fi network to show which other devices are using the same network. Copying is supported so you can save this information elsewhere. The SSID, BSSID, vendor, IP address, and subnet mask are shown for the Wi-Fi network you're on, and the IP address, mobile carrier name, country code, and MMC/MNS are given if you're connected to a cellular network. This free Wi-Fi app for iOS and Android devices shows you everything you could want to know about the Wi-Fi and cellular network you're connected to. ![]() Annoying footer ad overlays some content.
