Matching subdomains point to different CNAME targets

Two domains carry the same pair of subdomain labels: yzzcommon and 69f335c8397887d4. That repeated structure raises a concrete question: were the domains interchangeable routes to the same destination? DNS records supplied to CTX Threat Intelligence support a parallel naming scheme, but not a single demonstrated backend. The distinction matters because a useful infrastructure link can otherwise become an unsupported claim about redundancy or malware delivery.
