We are currently building a networking course with a practical part where students have to configure a small network in a virtual environment.
However, we are not sure what ipv6 prefixes we can use for the configuration. The IPv6 documentation prefix (
2001:db8::/32 RFC3849) seem to fit. However, someone brought up that this prefix should only be used in textual examples and never be actually configured anywhere, not even in an isolated test network. (Of course it would work, but could be seen as RFC violation).
The issue here is that the RFC is rather abstract about this and it all depends on how one interprets the term "documentation". I couldn't find any sources about the usage in experimental test/tutorial networks or the specification of "documentation" on the internet.
Can you help me out?
