The Domain Name System (DNS) has long provided means, such as the CNAME
(Canonical Name), whereby a DNS query can be redirected to a different
name.  A DNS response header has an RCODE (Response Code) field, used
for indicating errors, and response status bits.  This document
clarifies, in the case of such redirected queries, how the RCODE and
status bits correspond to the initial query cycle (where the CNAME or
the like was detected) and subsequent or final query cycles.  

This document is a product of the DNS Extensions Working Group of the IETF.

This is now a Proposed Standard Protocol.

protocol for the Internet community,and requests discussion and suggestions
