Comment(by zzchen_pku):

 Replying to [comment:2 jinmei]:
 Thanks for your quick reply.
 > Some initial feedback:
 >  - we should test the case where (some of) the NS name is out of zone.
 please also consider where to reject such case, i.e. within the Query
 class or delegate it to the underlying zone.  The former should be more
 efficient but requires more code.
 Added, I choose the former one.
 >  - likewise, we should test the case where NS name has a CNAME.
 Added.
 >  - shouldn't getAdditional()/findAddrs() be private?
 >  - getAdditional() can throw because getRdataIterator() or Zone::find()
 can.
 Right, updated.
 New change has been committed to r4091.
