IPv4 Range Aggregation

Just like the dedicated date range aggregation, there is also a dedicated range aggregation for IPv4 typed fields:

Example:

{
    "aggs" : {
        "ip_ranges" : {
            "ip_range" : {
                "field" : "ip",
                "ranges" : [
                    { "to" : "10.0.0.5" },
                    { "from" : "10.0.0.5" }
                ]
            }
        }
    }
}

Response:

{
    ...

    "aggregations": {
        "ip_ranges": {
            "buckets" : [
                {
                    "to": 167772165,
                    "to_as_string": "10.0.0.5",
                    "doc_count": 4
                },
                {
                    "from": 167772165,
                    "from_as_string": "10.0.0.5",
                    "doc_count": 6
                }
            ]
        }
    }
}

IP ranges can also be defined as CIDR masks:

{
    "aggs" : {
        "ip_ranges" : {
            "ip_range" : {
                "field" : "ip",
                "ranges" : [
                    { "mask" : "10.0.0.0/25" },
                    { "mask" : "10.0.0.127/25" }
                ]
            }
        }
    }
}

Response:

{
    "aggregations": {
        "ip_ranges": {
            "buckets": [
                {
                    "key": "10.0.0.0/25",
                    "from": 1.6777216E+8,
                    "from_as_string": "10.0.0.0",
                    "to": 167772287,
                    "to_as_string": "10.0.0.127",
                    "doc_count": 127
                },
                {
                    "key": "10.0.0.127/25",
                    "from": 1.6777216E+8,
                    "from_as_string": "10.0.0.0",
                    "to": 167772287,
                    "to_as_string": "10.0.0.127",
                    "doc_count": 127
                }
            ]
        }
    }
}
