Dns reverse lookup in elasticsearch 5.0.1

Elastic Stack Elasticsearch
1

Hi
I am using elasticsearch version 5.0.1 and centos 7.0
I want to resolve IP address to dns host name of my elasticsearch data. Is there any way to do it while uploading files to elasticsearch

I want to convert IP address of source,destination as host name.Is there any posiblity to do it
Doing dns resolve manually while uploading files takes more time since I push bulk records every time to elasticsearch db.

Thanks in advance
