I have a lookup table with a bunch of IP addresses (ipaddress.csv) and a blank column called hostname. I would like to search in splunk to find what hostnames each IP address have. I can find the hostnames in index=fs sourcetype=inventory. I'm just having a hardtime with the query logic of using the lookup table IPs to output to a table in splunk with their corresponding hostnames. Ideally I want to output the results in a table in splunk and add the hostnames back to the lookup table in the hostname column. Any help would be greatly appreciated! Thank you ... View more
