CNAME+DNAME Name Redirection
Internet Systems Consortium
This document updates RFC1034 to allow coexistence of the CNAME Resource Record with DNAME Resource Record at the same owner node, which provides redirection for a sub-tree of the domain name tree in the DNS system, in a parent zone. By allowing this cooexistence, DNS system will have a way how to create a sub-tree redirection together that includes the Resource Records owner name. This would allow parent zones to create full domain aliases.
