No it isn't. If you teach them to use a bogus internal pseudo-RFC1918 TLD
then the students will learn that it is OK to re-use the same
configuration everywhere, like they do for RFC1918 IP address space. If
you teach them how to choose a suitable internal subdomain of a
properly-delegated public domain then they should do that.
You can reinforce the point that different namespaces have different ways
of handling allocations for internal use if you also teach IPv6 and how to
properly allocate addresses in RFC 4193 IPv6 ULA space.
