    Description

      When RegistryDNS performs a lookup in an upstream DNS server and a CNAME record is retrieved, it returns a response with only the CNAME record (there is no A record, meaning no IP address is resolved). RegistryDNS should perform a lookup on the new name from the CNAME record in an attempt to find an A record, which would provide an IP address.
