	I still do not believe it is special, looking from DNS transport
	point of view.  situation should be either of the following:
	- exisitng ngtrans tools can support DNS situation,
	- existing ngtrans tools cannot support DNS situation, in this case,
	  other protocols need a new transition tool as well.
	and I guess the situation is the former.

	I wonder how you propose to solve transition issues with other problems
	in this situation (like accessing HTTPv4 servers).  if there's no
	soltion, we need a new tool in ngtrans toolbox (or toybox).

	also, in my view people will need to run dual stack (or "giant IPv6
	network with single IPv4 global address") for a very very long time.
	the view could be affecting my comments.
