IPv6 support in Portworx

Portworx supports IPv6 networking for Kubernetes deployments. This page provides guidance on supported platforms and known limitations. Use this information to ensure compatibility and optimal functionality in environments that require IPv6.

note

For OpenShift Virtualization, Portworx only supports IPv6 in dual-stack networking mode.

By default, Portworx uses IPv6 if the network interfaces it uses (for example, dataInterface and mgmtInterface) are configured with only an IPv6 address.

If the host uses a dual-stack configuration, you must explicitly configure Portworx to use IPv6. To configure IPv6 as the preferred network IP address, set the following environment variable in the StorageCluster specification:

env:
  - name: PX_PREFER_IPV6_NETWORK_IP
    value: "true"

Supported platforms

Portworx supports IPv6 on Red Hat OpenShift versions 4.15 and 4.16 on bare metal.

IPv6 limitations

The following features are not supported when using IPv6:

• Portworx installation behind a proxy
• Portworx Central License Server
• Portworx Backup
• Asynchronous and synchronous disaster recovery (DR)
