> A solution to this are IPv6 privacy extensions (which Debian enables by default if IPv6 connectivity is detected during initial installation), which will assign an additional randomly generated address to the interface, periodically change them and prefer them for outgoing connections. Incoming connections can still use the address generated by SLAAC.
Yeah. I've run several major Linux distros, Windows 10 and 7, and several major versions of OSX. All had "privacy addresses" on by default, which is annoying as shit.
