record[RNAME.IP.name] = {
         value = host,
         label = host,
         shown_label = host,
         reference = reference_html,
         country = interface.getHostCountry(host),
       is_local = alert_info.alert_generation and alert_info.alert_generation.host_info and (type(alert_info.alert_generation.host_info) == "table") and alert_info.alert_generation.host_info.localhost,
         is_multicast = alert_info.alert_generation and alert_info.alert_generation.host_info and (type(alert_info.alert_generation.host_info) == "table") and alert_info.alert_generation.host_info.is_multicast
     }
