LanScan
LanScan is a macOS network scanner for finding devices on local or configured IP networks and viewing their addresses, hostnames, and vendors.
What is LanScan?
LanScan is a macOS utility for scanning local networks and configured IP ranges to discover active devices. It is designed for users who want a quick view of computers, phones, printers, routers, and other hosts connected to a network. The app can show key details such as IP addresses, MAC addresses, hostnames, and hardware vendors, which makes it useful for basic network inventory, troubleshooting, and device identification. It also supports hostname resolution methods commonly used in mixed Apple, Windows, and business network environments. For people managing home, office, or lab networks, LanScan provides a focused way to inspect what is reachable on a subnet without using heavier network administration tools. LanScan is published by Iwaxx.

Safety overview
Status: Mostly safe
LanScan is a legitimate network utility, and scanning your own network is a normal use of this type of app. Because it inspects devices that respond on your network, it may reveal device names, addresses, and vendor details that are useful for administration but should still be treated as sensitive in shared environments. Use it on networks you manage or have permission to inspect, and review exported scan files before sharing them with others.
Recommendation: Keep LanScan if you use it to identify devices, troubleshoot connectivity, or maintain a home or office network. If you no longer need network scanning tools, you can remove it without affecting macOS, though any saved app-specific settings or exports you want should be kept first.
