      destructive up to moment of network node reboot or router
      delete/create), and check out if address will reply to ping.<br>
      <br>
      If 'yes' - means problems in routing/nat<br>
      If 'no' - means problem are outside openstack router (external
      net, provider routing, etc).<br>
