 This provides a wrapper to ping neutron guests that are on isolated
 tenant networks that the caller can't normally reach. It does so by
-creating a network namespace probe.
+using either the DHCP or Metadata network namespace to support both
+ML2/OVS and OVN.
 
 It takes arguments like ping, except the first arg must be the network
 name.
