      * Before this update, when installing a dual-stack cluster on bare metal using installer-provisioned infrastructure, the installation failed because the Virtual Media URL was IPv4 instead of IPv6. As IPv4 was unreachable, the bootstrap failed on the virtual machine (VM) and cluster nodes were not created. With this release, when you install a dual-stack cluster on bare metal for installer-provisioned infrastructure it uses the Virtual Media URL IPv6 and the issue is resolved.

      Description of problem:

      Customer is trying to perform Baremetal IPI installation. The ILO interface has ipv6 address but doesn't allow ipv4 connections.

Bootstrap fails and cluster nodes are not being created because the Virtual Media URL is unreachable as the URL is ipv4

This seems like a regression from an issue previously fixed

https://issues.redhat.com/browse/OCPBUGS-25996 https://github.com/openshift/installer/pull/7898 https://access.redhat.com/solutions/7052085

      Version-Release number of selected component (if applicable):

      OCP 4.18.21

      How reproducible:

      100%

      Steps to Reproduce:

          1. Deploy dual-stack cluster with IPv6 as primary
    2. Watch nodes boot
    3. You can see Virtual Media is using IPv4 instead of IPv6 like such: 

https://172.31.230.153:6183/redfish/boot-b2ce8680-c786-478f-bd35-688d475af410.iso

      Actual results:

      The Virtual Media URL is IPv4 (from the bootstrap VM) instead of IPv6

      Expected results:

      The Virtual Media URL should be IPv6
