Easy access to your IP addresses
IP Broadcaster displays your local (LAN) and internet (WAN) IP numbers in the menubar, with options to update these values at user-specified intervals.
By default, IP Broadcaster will associate the gathered data with the current active wifi network, but if the the host machine is not using wifi to connect to the network, the user may select which wifi SSID to associate the data with.
MAC Address Sharing
MAC addresses are the most reliable way to identify the devices on your network: unlike IP numbers, they are unique to each device. IP Scanner on macOS can read MAC address tables directly, but on iOS, visionOS and watchOS, platform privacy restrictions prevent native access to this data.
IP Broadcaster fills the gap. It gathers your Mac's MAC address tables and shares them directly with all your IP Scanner and IP Scanner Ultra clients, so every platform gets complete device identification with manufacturer lookup.
IP Broadcaster also serves as a lightweight, headless data provider for IP Scanner Ultra's exclusive Remote Scans feature. Just leave IP Broadcaster running on any Mac on your network - no need to keep IP Scanner open - and it continuously supplies fresh network data so you can monitor your devices from your iPhone or Apple Watch, even when you are away. This is a capability unique to IP Scanner Ultra that is not available in competing network scanner apps.
The sharing is automatic and instant: IP Broadcaster publishes the current MAC address cache both over your local network and via iCloud, tagged to your Wi-Fi network so each of your networks keeps its own set. IP Scanner clients pick up updates the moment they are published. You stay in control: choose how often IP Broadcaster refreshes and shares the tables, or turn sharing off entirely.
The app is free and extremely lightweight: it lives in the menu bar, launches at login, and just quietly does its job.
