    PVE hosts without IPv6 connectivity still try to use IPv6

    I have an issue with two Proxmox hosts which are misbehaving when establishing connections with pretty much anything. My own applications, apt, curl, ping, you name it. Both on the host and within LXC containers, things keep attempting to connect via IPv6, even though no IPv6 service is...

    Is a mixed IPv4/IPv6 (not dualstack, but some cluster hosts IPv4, some v6) possible?

    A very newbie question: I've got a purely v4 Proxmox cluster, and want to migrate it (the internal addressing used for corosync) to IPv6 as an end goal. Would it be possible to add a node with just a v6 address, and remove one v4 node, and so on? Or can this be done with dual stack addressing...
