IP Support

StarlingX supports IPv4 and IPv6 versions for various networks.

All platform networks must be a single address family, either IPv4 or IPv6, with the exception of the PXE boot network which must always use IPv4. The following table lists IPv4 and IPv6 support for different networks:

If present, the PXE boot network is used for PXE booting of new hosts (instead of using the internal management network), and must be untagged. It is limited to IPv4, because the StarlingX installer does not support IPv6 UEFI booting.

The Cluster Host network supports IPv4 or IPv6 addressing.

Data Network and SR-IOV Interface

There is no restriction for the Data Network and SR-IOV Interfaces to have the same address family as the platform. They operate independently from the platform and are capable of supporting both IPv4 and IPv6 addressing, offering flexible options for network connectivity. However, IPv4 or IPv6 requires dedicated IPAM pools or static address configuration to use the corresponding address families with the SR-IOV Interfaces. For more information about IPAM pools configuration, see https://docs.tigera.io/calico/latest/reference/resources/ippool.
