Abstract

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