Sometimes it's fine to do that, other times it isn't. If you plan to test network topology, firewalls, you can't do that. If you plan to run untrusted VMs, you also can't do that.
- okket 8y agoI'd use a unique local address network (/32) for this https://tools.ietf.org/html/rfc4193 https://tools.ietf.org/html/rfc4193
- 4ad 8y agoThat'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.
- okket 8y agoAt 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
- yardstick 8y agoTo 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.
