      Probably a notable technical change and not a bug fix:

      The `100.88.0.0/16` IP range is now the default private IP range. Customers should not use this IP range in their infrastructure network. (link:https://issues.redhat.com/browse/OCPBUGS-20178[*OCPBUGS-20178*])

    Description

      The IP range 168.254.0.0/16 that we chose as default for the transit switch is a public one. Let's use a private one instead, making sure it won't collide with address blocks already in use.

      In the future we might want to make this configurable, but for now let's just make sure we pick an IP range that is not used elsewhere in openshift.

          • Blocker - To be worked above all other priorities. This term is chosen when the severity of the issue is very high, has no workaround, or the effort for the change is comparatively low. Issues that may be very publicly visible and could generate significant media attention may also drive a higher priority.
