Happy in using Elastic Stack 5 with Ingest mode (Filebeat) now 🙂

I have a visualization (Data Table) to show all the source IP count to visit my web server.

clientip: Ascending Count  
1.10.100.151 1000  
1.10.100.152 1000  
1.10.101.153 500  
1.10.101.153 200  
1.10.200.160 30  
1.164.10.238 10

How can I group them by /24 subnet to become the list like below?

clientip: Ascending Count  
1.10.100.0/24 2000  
1.10.101.0/24 1000  
1.10.200.0/24 30  
1.164.10.0/24 10

Elasticsearch allows you to create [aggregation buckets](https://www.elastic.co/guide/en/elasticsearch/reference/current/search-aggregations-bucket-iprange-aggregation.html), including using a CIDR mask but it doesn't appear you can do it automatically. You might be able to create a custom [tokenizer](https://www.elastic.co/guide/en/elasticsearch/reference/current/analysis.html) to accomplish this.
