+    # Disable IPv4 DAD (Duplicate Address Detection / Address Conflict Detection).
+    # RHEL 10 enables this by default, which delays IPv4 address assignment by ~3s
+    # while ACD probing runs. This causes a race condition where
+    # nodeip-configuration.service may run before the IPv4 address is assigned,
+    # resulting in IPv6-only kubelet configuration on dual-stack clusters.
+    # See: https://issues.redhat.com/browse/OCPBUGS-86571
