OpenShift DNS follows a deterministic architecture: CoreDNS runs as a DaemonSet (not Deployment) managed by the DNS Operator, the cluster DNS IP is algorithmically derived as the 10th address in the service CIDR, cluster.local is reserved and cannot be used as a forwarding zone, and the full cluster DNS name follows `<metadata.name>.<baseDomain>` — making DNS both predictable and constrained.
DNS architecture is fully deterministic from the service CIDR — the IP, naming, and forwarding constraints form a closed system
