If you're okay with getting all IPs in an array field you can just use [grok](https://www.elastic.co/guide/en/logstash/current/plugins-filters-grok.html) extract all the IPs to a string and use the [mutate filter](https://www.elastic.co/guide/en/logstash/current/plugins-filters-mutate.html) to split that string.

```
filter {
  grok {
    match => ["message", "^(?<ip>%{IP}(, %{IP})*) ..."]
  }
  mutate {
    split => ["ip", ", "]
  }
}

```

It looks like you might always have at least two IPs, each followed by a space, followed by a comma-separated list of IPs. In that you'll have to adjust the filters a bit but it shouldn't be too hard.
