This is kind of unusual. Raspberry Pi 3 B+ with Aarch64 image. My SSH session keeps dying. I've noticed it happens about every half hour. When I log into the physical machine I see the IP address has changed.
Weird, I have around a dozen RPi 2/3 class devices on both wired and wireless network with a dual stack IPv4/IPv6 and I don't see that at all (and never have).
Nor have I had other reports.
This sounds like the IPv6 privacy option.

You are probably right.
I shutdown the radio with a command similar to 'dcicm radio off' and I stopped getting kicked of the wired LAN. I can't find the command in my Bash history, which is kind of odd.
Here was the command:
nmcli radio wifi off
That will turn the wifi off but if you're not connected to a wireless network it won't have any effect.
To disable IPv6 privacy on the wired interface you can do:
nmcli connection modify eth0 ipv6.ip6-privacy 0
There's a couple of blog posts with some good details: https://major.io/2016/04/17/enable-ipv6-privacy-networkmanager/ https://blogs.gnome.org/lkundrak/2015/12/03/networkmanager-and-privacy-in-th...
This device just keeps getting weirder. I miss the old days when things just worked...
Is it just the unstable addressing that's weird, or something else?
