Does Android leak MAC addresses via mDNS like iOS does?
Summary
So iPhone's WiFi Mac privacy protection never really worked as released in 2020, they apparently just fixed it in 17.1 after years of touting this privacy protection. I posted it here because I wonder if Android's implementation has received similar scrutiny.
Details
Android also uses Bonjour/mDNS, for example, the built-in mdnsd and the NsdManager
APIs https://developer.android.com/develop/connectivity/wifi/use-nsd
I imagine Android uses mDNS to find printers, Chromecast devices, etc. So I could see a case where an app uses the NsdManager
API, and that leaks the MAC. That would put Android in the same place as iOS. com.android.printservice.recommendation, com.android.bips, and adbd all support mDNS.
