I haven' t seen the original question, but, yes, the IDN routines are 
always used, if available. That means that every hostname being resolved 
is transformed according to the ToASCII rules, defined by RFC 3491.

For ASCII-only domains, this means mostly lowercasing, but also a few 
safety checks (all domain labels being non-empty and less than 64 
characters in length).
