When using ipam get-subnet-ip-inventory module the "dns-host-name" values are incorrect

The dns-host-name value returned from ipam get-subnet-ip-inventory is invalid. It is missing the Subnet and VCN domain portions and returning instead HOSTNAME.oraclevcn.com

% oci -v
3.50.3

% oci network ipam get-subnet-ip-inventory --subnet-id $SUBNET_ID --query 'data."ip-inventory-subnet-resource-summary"[*].{"ip-address": "ip-address", "dns-host-name": "dns-host-name", "ip-id": "ip-id"}'
[
  {
    "dns-host-name": "bastion.oraclevcn.com",
    "ip-address": "10.100.100.10",
    "ip-id": "ocid1.privateip.oc1.phx.abyhqljr7a5rvvwv7drl2cz67mw353xvevfbg5oprjj3oue2eyojfnwu43la"
  },
  {
    "dns-host-name": "vpn2-trusted.oraclevcn.com",
    "ip-address": "10.100.100.11",
    "ip-id": "ocid1.privateip.oc1.phx.abyhqljrygzwjrsshtlzcw5v3n5wcchh2nygdtjuk47sxbsxjlfsdnv6fyia"
  },
  {
    "dns-host-name": "tmp-mgmt-server.oraclevcn.com",
    "ip-address": "10.100.100.12",
    "ip-id": "ocid1.privateip.oc1.phx.abyhqljrvezqcifixpog6meuea75yp6ztfb4urnv3mznmnhqcypynjl2dxoq"
  }
]

Each above should have the domain name of the Subnet attached:

% oci network subnet get --subnet-id $SUBNET_ID --query 'data."subnet-domain-name"'
"app.vpnphx.oraclevcn.com"

Thus, should have names like

• bastion.app.vpnphx.oraclevcn.com
• vpn2-trusted.app.vpnphx.oraclevcn.com
• tmp-mgmt-server.app.vpnphx.oraclevcn.com

…instead of what we see now like this:

• bastion.oraclevcn.com
• vpn2-trusted.oraclevcn.com
• tmp-mgmt-server.oraclevcn.com

Start by running oci network ipam get-subnet-ip-inventory and compare each dns-host-name with the subnet-domain-name returned by oci network subnet get. Trace the CLI entry point for the IPAM inventory response and identify where the hostname is assembled. Done means the inventory output includes the subnet and VCN domain portions shown in the issue.
