I have pointed my domain to use Oracle & Netlify nameservers only. However, when I do a reverse DNS look up for PTR records, it says NXDOMAIN and it's reported by ns1.p24.dynect.net which is Dynadot Nameserver. For every other check, it defaults to the Oracle nameserver. How can I make it use the Oracle nameserver for PTR where the reverse DNS record is actually defined?
