What Is Network Discovery Software?

Network discovery software allows network administrators to collect relevant data on all network devices. Its importance has grown hand in hand with the average network size. It’s no longer feasible for network administrators to manually create network maps using tools like Microsoft Visio or SmartDraw. They need a software solution that can automatically provide visibility and help them be one step ahead of their network’s growth.

Network Discovery Tools often gather basic system information on network devices using the Simple Network Management Protocol (SNMP) protocol. Devices that typically support SNMP include cable modems, routers, switches, servers, workstations, printers, and others.

“SNMP network discovery exposes management data in the form of variables organized in a management information base.”

In Windows 10, you can turn on network discovery via SNMP from the “Turn Windows features on or off” list located in Control Panel → Programs and Features. Keep in mind that SNMP network discovery is different than network discovery Windows 10, which can be activated from Advanced Sharing Settings and allows Windows 10 to find other computers and devices on a network.

How to Choose the Best Network Discovery Tool?

The demand for network discovery tools is huge, and there are many solutions available to network administrators and regular users alike, some of them good and some not. When choosing a network discovery tool, there are certain things you should always pay attention to.

  • Vendor-neutral: Also known as proprietary lock-in or customer lock-in, vendor lock-in makes a customer dependent on a vendor for products and services. When you become dependent on a single vendor, you can’t readily use another vendor without substantial switching costs. Today’s networks are increasingly heterogeneous, which is why you should always choose a network discovery tool that’s vendor-neutral can capable of discovering and monitoring devices on your network regardless of vendor.

  • Performance reports: The best network discovery tools don’t stop at data gathering. Instead, they help you make sense of your network and its performance by providing customizable performance reports that can be used for troubleshooting and presentations. Some network discovery tools can even proactively detect security, software licensing, and other issues, keeping your network safe.

  • Flexible pricing: Excellent free network discovery tools do exist, but their real cost is typically higher than the cost of paid network discovery tools, which often include premium customer support. Instead of trying to find the cheapest network discovery tool available, it’s a much better idea to look for network discovery tools with flexible pricing, so you can pay only for what your really need.
