PhoneBridger uses python-zeroconf 0.151.5 (LGPL-2.1-or-later) and ifaddr 0.2.0 (MIT) for local network discovery.

Unmodified upstream source and build instructions:
https://github.com/python-zeroconf/python-zeroconf/tree/0.151.5
https://github.com/pydron/ifaddr/tree/0.2.0

The library files are in the portable package _internal directory. PhoneBridger build requirements pin the exact versions; the included licenses describe redistribution and modification rights. Discovery is not authentication: PhoneBridger independently verifies the saved TLS fingerprint before sending credentials.
