I'd use a unique local address network (/32) for this https://tools.ietf.org/html/rfc4193 https://tools.ietf.org/html/rfc4193

  That's fine for some scenarios, but in general for my use cases, I wouldn't, because most often I want my VMs to be accessible from the Internet.

    At this point I'd argue your case is a bit special and you may need special arrangements. If it is that critical for you to have a gazillion of IoT devices and untrusted VMs accessible from the internet via IPv6, get a /48 tunnel from he.net

      To be fair, his special case just works on IPv4, but not on IPv6. So it’s a regression in functionality without the right prefix size.
