In Oracle Cloud Infrastructure (OCI), peering Virtual Cloud Networks (VCNs) with overlapping IP addresses is not permitted. This is because overlapping IP ranges would create routing conflicts that could lead to ambiguity in traffic direction and could disrupt the expected communication between the peered networks.

When VCNs are configured to peer with each other, they need to have distinct IP address ranges to ensure that there is a clear and unambiguous path for traffic to traverse from one network to another. Overlapping IPs would defeat the purpose of having separate networks and could complicate network management, leading to potential connectivity issues or misrouted packets. Hence, the requirement for non-overlapping IPs is a fundamental design choice in OCI that promotes network reliability and clarity in routing.
