I have been unable to register a cname that the lookup is required for a service. Using this I checked the cname https://www.ultratools.com/tools/dnsLookupResult
Nothing comes up on two different domains I have. All cname entries are greyed out. I know an A record will do the same but this wont work as the service I am using is requiring a cname lookup. Of course with the cname flattening cant be turned off, Im not sure how to get this to register.
