Can splunk perform a command similar to nslookup? i have the host names just need to tie them to an ip address.
What you are wanting to perform is a standard dns lookup then, hostname/fqdn to ip address. Splunk can do this, and reverse (ip to hostname/FQDN) lookups quite easily.
Refer to : http://docs.splunk.com/Documentation/Splunk/6.2.1/Knowledge/Addfieldsfromexternaldatasources#Externa...
Gives the full process for implementing and performing both Standard and Reverse lookups.
