DNS/1/response/name_errorについて、ここに記述してください。

If recursive service is requested and available, the recursive response
to a query will be one of the following:
{{{
   - The answer to the query, possibly preface by one or more CNAME
     RRs that specify aliases encountered on the way to an answer.

   - A name error indicating that the name does not exist.  This
     may include CNAME RRs that indicate that the original query
     name was an alias for a name which does not exist.

   - A temporary error indication.
}}}


If recursive service is not requested or is not available, the non-
recursive response will be one of the following:
{{{
   - An authoritative name error indicating that the name does not exist.

   - A temporary error indication.

   - Some combination of:

     RRs that answer the question, together with an indication
     whether the data comes from a zone or is cached.

     A referral to name servers which have zones which are closer
     ancestors to the name than the server sending the reply.

   - RRs that the name server thinks will prove useful to the requester.
}}}
