Support
Subnet Scout is a native app for Mac, iPhone, and iPad that discovers devices and services on your local IPv4 network.
Before scanning
- Allow Local Network access when your device asks.
- Select the detected network or enter a valid IPv4 CIDR range.
- Make sure your device is connected to the network you want to scan.
If a device is missing
Sleeping devices, client isolation, firewalls, VPN routing, and separate network segments can prevent discovery. On iPhone and iPad, check that Subnet Scout is enabled under Settings > Privacy & Security > Local Network.
Platform differences
On Mac, MAC addresses and vendor names are best effort and normally require the device to be on the same local network segment. iOS and iPadOS do not expose the system neighbor table to apps, so MAC addresses and vendor names are unavailable on iPhone and iPad. Bonjour discovery on iPhone and iPad is limited to service types declared by the installed app version.
Sharing and Mac exports
On Mac, use the Share menu to export visible results as CSV or JSON. On iPhone and iPad, use the share button on a device to share its IP address. Information is shared or saved only when you choose to do so.
