(EMCONetworkInventory is a set of simple-to-use but powerful network tool software, which will not leave traces on the access process of remote computers. The software can quickly and effectively generate detailed reports of computer software, hardware and version status including tracking, comparison and control of the application status of the license in the local area network. During the whole process, the material flow in the local area network is relatively small. The software uses 3 ways to scan all online devices and domains on the network: 1. Scan all devices and all domains; 2. Scan according to a given IP address size; 3. Scan according to a given domain name . Scanning results can be made into a local network message material library or saved as an Excel file. At the same time, it can also directly print, text documents, PDF documents, HTML documents, JPEG pictures and other formats of presentation output.)
