[ipcat](https://github.com/client9/ipcat/) is a project for classifying IP : "Datacenter or not", and which provider.

Here is the optimized filter for logstash :

> **[bearstech/logstash-filter-ipcat](https://github.com/bearstech/logstash-filter-ipcat)**
>
> logstash-filter-ipcat - Is this IP came from a datacenter?

Same usage as geoip.

You can use something like that :

```auto
input {
    # get some apache log
}

filter {

    ipcat {
       source => "clientip"
       #default target is "ipcat"
    }

}

output {
    if [ipcat] {
        file {
            path => "/var/log/logstash/ipcat.log"
        }
    }
}

```
