With 5.x ipv6 is supported in the IP type field now. However, it seems Kibana did not keep up.
If I remove my string fields and rely only on the ip type field in my ES mapping, and try to aggregate on it using Kibana, I can only aggregate on the ipv4 range type, and any other aggregations remove any ip fields from available terms.
Is it the same in 6.x too? Why is this not mentioned in any of the documentation?
If it is in the documentation, it must be extremely buried because I can find no mention of "We support IPv6 in ES but not in Kibana visualizations"
edit: I played with this a bit more, and seems I can aggregate using "terms" but not "significant terms"
