Generate and use temporary IPv6 addresses

Browse Source 
Temporary addresses are privacy-preserving for outgoing traffic, as they
don't disclose the MAC address.

The MAC-derived IPv6 stays, so clients (e.g. IP-based remotes) have a
permanent IPv6 as before.
Servers, including local ones, will see changing IPv6 addresses when
contacted by LibreELEC. Users who don't like this may revert this
setting.
