+++ This bug was initially created as a clone of Bug #2004081 +++

Description of problem: OCP explicitly does not allow the use of the following reserved address blocks.


If the render command observes these in the install-config as machineCidr it should fail and provide a clear message to admin.


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

How reproducible: 100%

Steps to Reproduce:
1. create a cluster with machineCidr defined using one of the ranges above
2. cluster will fail to bootstrap because we will skip these endpoints in the observers used by the control-plane operators[1].

Actual results: bootstrap fails for an unknown reason.

Expected results: bootstrap fails early as possible with a clear message indicating the address range is unsupported.

This bug hasn't had any activity in the last 30 days. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet. As such, we're marking this bug as "LifecycleStale" and decreasing the severity/priority. If you have further information on the current state of the bug, please update it, otherwise this bug can be closed in about 7 days. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant. Additionally, you can add LifecycleFrozen into Whiteboard if you think this bug should never be marked as stale. Please consult with bug assignee before you do that.
