there is a field named ip, which mapped to ip type, now i want to aggs as /24 subnets, i use script "doc['ip'].value & 0xffffff00" to get long value of ip, how to next to convert it to ip string???

```
{
  "_source": [
    "host",
    "ip"
  ],
  "aggs": {
    "ip_subnet": {
      "terms": {
        "script": "doc['ip'].value & 0xffffff00"
      }
    }
  },
  "size": 0
}

```

I didn't found any result from elastic website, I wonder know if there is another way to receive the subnets aggs?

I also tried doc['ipstr'].value.split('.')[0..2].join('.') but also not work.

Thank you very much, and forgive my pool english 😉

Why would you want to change it to a string? You should be able to do [bucket aggregations on ip type](https://www.elastic.co/guide/en/elasticsearch/reference/current/search-aggregations-bucket-iprange-aggregation.html).

thank u for reply.

I want to group by ip's subnet, not just ip. and ip range it's not suite cause i don't know the range, just wanna group by all subnet.

But you can group by subnet, as [defined in the document I linked previously](https://www.elastic.co/guide/en/elasticsearch/reference/current/search-aggregations-bucket-iprange-aggregation.html). Note the CIDR netmask/subnet filter in this example:

> { "mask" : "10.0.0.127/25" }
> ]
> }
> }
> }

I'm not sure in that case, but I don't think there's anything built-in that will do that for you (at least not one that's accessible). You might find something and script it out, as there are converters back and forth on that count.
