I want to remove this ipv6 info ,How? THANKS!

I try to remove ipv6 info with script :slight_smile:

  - script:
      lang: javascript
      id: my_filter
      source: >
        function process(event) {
            var message = event.Get("host.ip")
            event.Put("len",message.length)
            for (var i=0; i<message.length; i++)
            {
                if (message[i].indexOf("192.") > -1)
                {
                    event.Put("host.ip",message[i])
                    break;
                }
            }
        }

but recevie:

I could not reproduce the panic on the latest version. Please try a newer release.

function process(event) {
            var message = event.Get("host.ip")
            event.Put("len",message.length)
            for (var i=0; i<message.length; i++)
            {
                if (message[i].indexOf("192.") > -1)
                {
                    event.Put("host.ip",message[i])
                    break;
                }
            }
        }

Is there any problem with the code?

That code works. Of course there are other ways to implement this, but it puts the first 192 address into host.ip and returns.

what is other ways?
