Hi,

I have an interesting use case!(of course, it might not be interesting for others 😛) i am sending packet beat flow data to elastic search. While analysing the data in kibana i want few custom tags so i opted for scripted fields. But, the problem is i have source.ip and dest.ip in each indexed document and want to assign a name based on these ips dynamically by getting these ip to host mapping from a centralised place. can i do that in painless or is there any alternative to that?

@Venky_Guntakindapall there's not a way to do that using scripted fields currently, however you can use the [Dns filter plugin](https://www.elastic.co/guide/en/logstash/current/plugins-filters-dns.html) in Logstash to do so. The other benefit that you get from doing this in Logstash when you're indexing the data is that the searches will be much faster.
