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](http://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

You need to use Logstash for that./

Thanks for your reply
I parse data manually in python according to my format and push it to elasticsearch using curl command.
Thanks in advance

Why not just use Logstash for all of that?
