+## Designated IPs used by Arc resource bridge
+
+When Arc resource bridge is deployed, there are designated IPs used exclusively by the appliance VM for the Kubernetes pods and services. These IPs can only be used for Arc resource bridge and can’t be used by any other service. If another service already uses an IP address within these ranges, please submit a support ticket.
