Hi,

I have a field - **src-station-id** in the logs that brings in **IP** and **Hostnames** as string.  
Now in order to create a new field when src-station-id only contains IP, I am trying to get a script processor identify that as IP or String.

```auto
def fieldValue = ctx.src-station-id;
          if (fieldValue != null) {
            if (fieldValue instanceof String) {
              if (fieldValue =~ /^(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)$/) {
                ctx.sourcefieldType = "IP";
              } else {
                ctx.sourcefieldType = "String";
              }
            } else {
              ctx.sourcefieldType = "Not a String";
            }
          }

```

If _ctx.sourcefieldType = IP_ , src-station-id will be converted to **source.ip** as IP type once identified correctly.  
For some reason this script processor does not detect the IP correctly all the times. There must be a better way to handle it. Please suggest 🙂
