We know it's not TXT or AAAA, narrows it down to two. CNAME gives us the DNS canonical name, has nothing to do with dns zone. PTR by default, google says the same thing

A DNS pointer record (PTR for short) provides the domain name associated with an IP address. A DNS PTR record is exactly the opposite of the 'A' record, which provides the IP address associated with a domain name. DNS PTR records are used in reverse DNS lookups.
