Comment:

 There is an undocumented behavior which allows RData to be added to
 currently any class RRSet.
 The addRdata(const RdataPtr&)  variant, will simply add the RDataPtr
 without making a copy of
 the underlying object as do other variants.   It is in this object copy
 that the failure was occurring.  The following snippet currently works for
 any RRClass:

 {{{
         dns::rdata::ConstRdataPtr rdata;
         if (ncr_->isV4()) {
             rdata.reset(new dns::rdata::in::A(ncr_->getIpAddress()));
             rrset->addRdata(rdata);
         }
 }}}

 However, this is not 100% correct.  A new ticket is being opened which
 will add validation to
 this variant that will allow class the matching class as well as class
 NONE.

 This ticket is closed.
