What are Network Discovery Tools?
Network discovery tools, also known as network scanners, are software applications that allow users to identify online devices, services and networks on a particular network. They typically do this by using protocols such as ICMP, TCP or UDP to discover the IP addresses associated with those devices. In some cases, they also provide additional information about the discovered devices, such as their operating system and hardware specifications. Compare and read user reviews of the best Network Discovery tools currently available using the table below. This list is updated regularly.
