> 1. Is it possible to use the same subnet on different innernets?

As moviuro mentioned, no, not unless you want to get fancy with independent network namespaces (https://man7.org/linux/man-pages/man8/ip-netns.8.html).

If you want to be more confident of not having an address space conflict, I recommend using a randomly generated private IPv6 block using the RFC 4193 specification: https://en.wikipedia.org/wiki/Private_network#Private_IPv6_a...

> 2. Could you please provide installation instructions for generic linux, as I am looking to host on almalinux and opensuse leap, neither of which use dpkg.

Our Arch PKGBUILD (https://aur.archlinux.org/cgit/aur.git/tree/PKGBUILD?h=inner...) may be the simplest existing guide for making your own package for your distro. If it's not a lot of work to add, I'm happy to maintain other package formats, or help you be a maintainer.

Thanks! Looking forward to hearing how it goes for you.
