+    *Classless static routes* can now be configured for ironic inspector
+    subnets. The ``dnsmasq_ip_subnets`` has been extended to support the
+    ``classless_static_routes`` key in a subnet defention. This allow advanced
+    routing options to be pushed to the inspection ramdisk. For example::
+
+      dnsmasq_ip_subnets = [
+          { 'tag'                     => 'subnet2',
