Converting HOST records to A + PTR record

[#1]

I would like to get all HOST records in a DNS View via WAPI and after that, convert every single Host record in A record + PTR record in order to import these records in other DNS Server don't supporting Host records.

I can get HOST records without any problem and I also get the associated fqdn but I'm not able to get the associated reverse zone (therefore PTR record).

Does anyone know how to get this information starting from host record?

Thanks!

A host doesn't "have" a PTR, but instead it causes a PTR to be synthesized.   It's the same thing with the A or AAAA or CNAME records.  You will just need to get all the records, and potentially aliases, within the host and then generate the A, PTR and CNAME records that would have been synthesized.
