      Trying to deploy a HostedCluster using an IPv6 network, the control plane fails to start. These are the networking parameters for the HostedCluster:
      
        networking:
          clusterNetwork:
          - cidr: fd01::/48
          networkType: OVNKubernetes
          serviceNetwork:
          - cidr: fd02::/112
      
      
      When the control plane pods are created, the etcd pod will remain in crashloopbackoff. The error in the logs:
      
      invalid value "https://fd01:0:0:3::4c:2380" for flag -listen-peer-urls: URL address does not have the form "host:port": https://fd01:0:0:3::4c:2380
