This image shows an OCI Region with a Central VCN and a subnet containing a private DNS zone listening to a public DNS zone.

The subnet with IP address 10.0.0.0/24 includes two servers SRV1 x.2 and SRV2 x.3.

It also includes a Private DNS Resolver Listener with IP address 10.0.0.4 for resolving DNS queries for private IP addresses within the VCN.

The public DNS zone which the private DNS rssolver is listening to holds the records for SRV1 and SRV2. The public DNS zone shows the following two domains:

• oraclevcn.com. SRV1 - A with the IP address 10.0.0.2
• ocizone.internal contains app 1 - A with IP address 10.0.0.2 and app 2 - A with IP address 10.0.0.3
