I need to create a pointer record (PTR) for a reserved public IP address provided by Oracle.
I checked article Setting Up Reverse DNS Zones in Oracle Cloud Infrastructure Documentation.
I attempted to create the reversed DNS zone following the instructions provided in that article, but I receive the following error message:
Authorization failed or requested resource already exists.
For example, let's say my reserved public IP address is 18.104.22.168. I have already tried creating the following DNS zones: 193-22.214.171.124.in-addr.arpa and 193.193.193.in-addr.arpa. But I receive the above error message.
I only need this for this particular record.
