How to map an IP to a hostname in the splunk hosts list?

[the_wolverine]

My understanding is that this is now done via a splunk config file. How?

You could do this via a lookup table - http://docs.splunk.com/Documentation/Splunk/5.0/Knowledge/Aboutlookupsandfieldactions

or via a tag - http://docs.splunk.com/Documentation/Splunk/5.0/Knowledge/Abouttagsandaliases
