### A clear and concise description of what happend.

I want to deploy a standalone cluster of k8s and with calico's ipv6, but I found index out of range [0] with length 0 error. May i ask does kubekey support ipv6? or is my configuration wrong? I would be delighted to receive a response，thx

### Additional information

_No response_

Start with cmd/kk/pkg/core/util/ip.go, especially networkRange, GetAvailableIP, and ParseIp, then trace their use from GenerateCertSANs in cmd/kk/apis/kubekey/v1alpha2/cluster_types.go. Reproduce the supplied IPv6 Calico configuration and determine whether the result should support it without panicking or report a clear configuration error.
