CNAMEs wont work for their use case, but it seems like DNAMEs might. However DNAMEs work at the (sub)domain level to alias a series of records, not just one.

- aeden 15y agoWe considered DNAME records, however a DNAME only redirects subdomains: Unlike a CNAME RR, a DNAME RR redirects DNS names subordinate to its owner name; the owner name of a DNAME is not redirected itself. Thus for this to work for a second-level domain the redirection would have to occur at the top-level domain. In essence the behavior is not what is needed for this particular problem.
