I have uploaded some syslogs through logstash into Elasticsearch and I am visualising these logs with Kibana 4.5.1. One of the fields is the destination IP and I have configured that as an IP address in Elastic ("type" : "ip"). Now I'm interested in finding the broadcast messages by searching for all messages with a destination IP ending with 255. I have tried entering Source_IP:*.*.*.255 in Kibana but this gave me the following error message: NumericTokenStream does not support CharTermAttribute. Is there another syntax for doing this?
