If the matter is security related, please disclose it privately via --Is this a BUG REPORT or FEATURE REQUEST?: What happened: PR tries to reduce CNI calls for sandboxed containers: case is for Windows Server 2016 and for Windows Server version greater than 1709 which use Hyper-V containers. Currently, the CNI on Windows fetches the IP from the containers within the pods regardless of the mode. This should be done only in the non-sandbox mode where the IP of the actual container will be different than the IP of the sandbox container. from the same pod will share the network details of the sandbox container. when this mode is supported. However, for Windows 1709 and 1803 we didnt have the Namespace support in Windows which we are bringing in RS5. So we need this second call to replicate the DNS registry key to the Workload container. This is a platform requirement and removing this will break DNS for the workload containers. IP/Gateway/MAC is set separately than DNS. (Refer ) In Rs5 once we move the namespace model, we will update CRI and CNI to add endpoints and add it to the namespace. So the PR breaks dns for windows containers. We should revert it. /sig windows /kind bug
