use of (the term) NAT considered dangerous

since usually you mean NAPT. Realistically speaking, almost every NAT 
that's out there in the real world is actually a NAPT. In fact I think 
that NAT is so rare that it really should be called NA(!P)T to be 
completely clear that there is no port translation going on.
