All my Proxmox containers lost IPv6 connectivity. The addresses were no longer reachable. Had to restart all of them. Why?
Also, DNS stopped working all across my network. Why? Because after the Turris OS upgrade, there was a new DHCP option configured in Luci:
6,192.168.100.1/24
Which caused all my devices to grab this address for their resolv.conf:
24.192.168.100
What the hell? I have never created such an entry. What is happening here? What more peculiar behavior am I about to experience with this - of course well tested - update?
