    Yeah, no.

    I’m not going to LD_PRELOAD some random library into my SSH process, and I’m definitely not going to export LD_PRELOAD as a global environment variable.

    Couldn’t this be setup with some kind of virtual IPv4 interface that routes to your IPv6? I guess you’d need some kind of driver to add the prefix.

    Edit: I think this is supported by the standard 4-in-6 tunnel interface: https://serverfault.com/questions/422791/which-software-could-i-use-to-setup-a-4in6-ip-tunnel-rfc-2473-on-gnu-linux

      Yeah I’m pretty sure with some simple virtual network bridges and routing rules a 4-to-6 converter is plenty possible without touching the actual processes.
