Hi,

Im using Kibana 5.4.0  
I have field `netflow.ipv4_dst_addr`. I want check this is private ỏ public ip.

Here is my script filed

> def m = ^(?:10|127|172.(?:1[6-9]|2[0-9]|3[01])|192.168)..\*$/.matcher(doc['netflow.ipv4\_dst\_addr'].value);  
> if ( m.matches() ) {  
> return "private"  
> } else {  
> return "public"  
> }

but kibana show compile error

Since this seems to be a static pattern, why not add a field at ingest time? This is likely to perform and scale better than a scripted field.
