+==== Change in the IP address range that Open Virtual Network Infrastructure Controller uses
+
+In the {product-title} 4,13 release, the `168.254.0.0/16` IP address range was the reserved IP address range that the Open Virtual Network Infrastructure Controller used for the transit switch subnet. For {product-title} {product-version}, the Open Virtual Network Infrastructure Controller uses `100.88.0.0/16` as the reserved IP address range. The `100.88.0.0/16` range must not conflict with any connected networks. See link:https://issues.redhat.com/browse/OCPBUGS-20178[OCPBUGS-20178] and xref:../networking/cidr-range-definitions.adoc[CIDR range definitions].
