AssetLoom Network Scanner

AssetLoom Network Scanner is a free, standalone command-line tool for agentless network discovery. It's built by AssetLoom, but it works on its own, you don't need an AssetLoom account or subscription to use it. It runs a local scan using ARP, ICMP, TCP, DNS, NetBIOS, and mDNS to identify IP addresses, MAC addresses, hostnames, vendors, open ports, and device types. Export the results as CSV or JSON and plug them straight into whatever inventory process you already use. No agents to deploy.

No credentials to hand over. No data leaving your network. Anyone managing a network can run it, whether or not they use AssetLoom for anything else.
