The IPv4/IPv6 dual stack in Kubernetes:

Dual-stack networking assigns both address types; it does not translate requests between IPv4 and IPv6 services itself.

You cannot access an IPv4 address directly using an IPv6 address; they are distinct address families.

While NetworkPolicies are important for security, dual-stack itself does not inherently *require* them to prevent mixing requests, as services are typically configured to expose specific protocol families.

With IPv4/IPv6 dual-stack, Kubernetes allows services to be configured with both IPv4 and IPv6 addresses, enabling endpoints (Pods) to be reached via either protocol. This feature supports modern network environments where both address families are in use.
