Yes - going down this route is a mistake. Don't do it. I speak from 
personal experience.

First, it conflicts with a possible future standardisation of mDNS.

Second, if you ever need to bring the hosts into your "real" DNS at a 
future date, you'll find you've made your life really hard, needing 
DNSSEc trust anchors, forwarders/stub statements, and so on.

Pick a private sub-domain of a *real* domain that *you* own e.g. if you 
are "", pick:

...and sidestep this at the planning stage. You can easily make that 
zone hidden by delegating it to nameservers which are only reachable 
from the appropriate places, or by using "allow-query" ACLs or similar.
