It's an LTE device so it doesn't have a MAC address even though it presents an ethernet-like interface. Or I guess it's the qmi-wwan driver which does that. Random generation seems likely since the number is not the device serial or IMEI, at least. > Is that number always the same? It's only happened twice so far, the other time it was wwx0a87b909a663 instead of wwx0a697e2d934f so probably random. > I'm wondering if there is a MAC randomisation process running on you > system (sometimes used for privacy concerns) and that randomisation > may be during boot with different timing compared to systemd/udev > renaming the device from wwan0. I'd assume no, other interfaces don't seem to be affected. I definitely didn't install anything like that so only if it's a default in Debian.
