LanScan Overview
LanScan is an IPv4 and IPv6 network scanner for Mac from iwaxx Sarl. It discovers every active device on a subnet, whether that's your local network or a public IP range you configure. Results show each device's IP address, MAC address, hostname, and manufacturer, pulled from a regularly updated vendor database. Custom hostnames and comments label unidentified devices, and everything exports to CSV for later reference. IPv6 support covers both Link-Local and Global addresses. iCloud sync keeps custom names consistent across every Mac running the app. The free version works fully, though some fields are obfuscated until a Pro in-app purchase unlocks them.
Why Choose LanScan Mac App
Most routers list connected devices in a basic table, if they show anything at all. LanScan goes further. It scans an entire IPv4 range, or just the local subnet, and pulls back the IP address, MAC address, hostname, and vendor for every device it finds. Custom hostnames and comments make sense of unlabeled devices, and everything exports to CSV for record-keeping or troubleshooting later.
Apple has tightened access to certain networking data in recent macOS betas, including ARP table access needed for MAC address lookups. LanScan's developer tracks these changes closely. A workaround for one such restriction shipped within weeks of it appearing in a macOS 27 beta. That kind of fast turnaround matters for a tool whose entire job depends on low-level network access still working properly.
Key Features
- Auto-detects network interfaces: finds Wi-Fi, Ethernet, and virtual interfaces automatically before scanning starts.
- Custom IP range scanning: scans anywhere from a single address to the entire IPv4 address space.
- ARP-based local scanning: discovers devices on the local subnet using ARP packets for speed and accuracy.
- Ping, SMB, and mDNS scanning: reaches devices on public IP ranges using multiple discovery protocols.
- IPv6 address discovery: displays both Link-Local (private) and Global (public) IPv6 addresses.
- Hostname resolution: resolves names via DNS, mDNS for Apple devices, and SMB for Windows devices.
- Custom hostnames and comments: labels unidentified devices with names and notes that persist between scans.
- Public IP lookup: shows your own public IPv4 and IPv6 address, along with the country and provider they resolve to.
- MAC vendor database: identifies device manufacturers from their MAC address, updated regularly with new entries.
- iCloud sync: keeps custom names and comments consistent across every Mac running LanScan.
- CSV export: saves scan results to a file for reporting or further analysis.
- Customizable columns: shows, hides, reorders, and aligns result columns to fit a particular workflow.

What's New in LanScan 8.2.16 Version
Version 8.2.16, released in September 2026, adds a networking detail alongside stability fixes:
- Public IP address now displayed in the Details pane, covering both IPv4 and IPv6, along with the country and internet provider they resolve to
- Six crashes fixed
- MAC vendor database updated with 216 new manufacturer entries
- MAC vendor database updates land in nearly every release, since new hardware manufacturers register new address blocks on an ongoing basis.
Supported macOS Versions
LanScan requires macOS 12 (Monterey) or later. That minimum was raised from an earlier, lower requirement so the app could keep pace with how macOS handles low-level networking data. Since scanning is mostly a network-bound task rather than a CPU-heavy one, an older Mac scans a subnet just as capably as a new one. Scan speed depends far more on the size of the IP range and the local network than on the Mac's processor.
How to Download and Install LanScan on Mac?
Installing LanScan on Mac takes under a minute through the App Store, with no separate download or setup involved.
- Click the Download button above. It opens LanScan's official listing on the Mac App Store.
- Click Get to download, since the base app is free.
- Sign in with your Apple ID if prompted.
- macOS downloads and installs LanScan automatically in the background.
- Once installed, launch it from Launchpad or your Applications folder.
The free version scans and displays results with some fields obfuscated. Purchasing the relevant Pro upgrade through the app's Help menu reveals them in full.
How to Use LanScan Mac App?
- Choose a network interface from the Config menu, such as Wi-Fi or Ethernet.
- Set the IP range to scan, or leave it on the default local subnet.
- Click Start to begin scanning; results populate the list as devices respond.
- Click a device to add a custom hostname or comment for future reference.
- Right-click a result to open its custom URL, if one is configured, directly in a browser.
- Export the finished results to CSV from the File menu for records or reporting.
