right, like this junk:

seems like rfc1918's prohibitions are not effective (and are unenforceable).
i hope that there will be no more ops-relevant specs with harmful potential
side-effects and ineffective+unenforceable prohibitions against those.

and of course, see BCP38 (or if you're in management, SAC004).
