IP Scanner
IP Scanner is a network utility for Mac that scans local networks to list connected devices, helping you identify hosts, addresses, and services.
What is IP Scanner?
IP Scanner is a native network scanning and monitoring app for Mac that helps you discover devices connected to your local network. It is designed for users who want to identify computers, phones, printers, routers, media devices, and other hosts on the same subnet, whether for home troubleshooting or more advanced network administration. The app can show details such as IP addresses, MAC addresses, vendor information, and device names, and it includes tools for rescanning and inspecting network results more closely. It also supports workflows such as recognizing trusted devices, spotting unknown hardware, and opening related actions or helper tools for deeper investigation. IP Scanner is published by 10baseT and is also available across other Apple platforms, but the Mac version is focused on desktop network discovery and analysis.

Safety overview
Status: Mostly safe
IP Scanner is a legitimate network utility whose network access is consistent with its purpose. On Mac, it may request local network access and use scanning-related features to discover nearby devices, which can reveal information about systems on your network such as device names, addresses, and vendors. That behavior is expected for a network scanner, but you should only use it on networks you own or administer and review any helper-tool or plugin settings before enabling them.
Recommendation: Keep IP Scanner if you use your Mac to inventory devices, troubleshoot Wi-Fi or LAN issues, or monitor your local network. If you no longer need network scanning tools, you can remove it without affecting macOS, though any saved device labels, lists, or preferences in the app will no longer be available.
