Splunk Search

How do I create a list of unique IPs from an access log file to compare to a Audit log event?

I have some web access logs that look like this:

10.0.0.134 - - [31/Aug/2017:08:07:40 -0600] "GET /images/MXALoginBG.jpg HTTP/1.1" 200 54665 "https://prod.MXA.com/" "Mozilla/5.0 (X11; Linux x86_64; rv:46.0) Gecko/20100101 Firefox/46.0"

And I need to get all of the unique IPs listed into a single list so I can look them up and determine where they are from and if the same user and corresponding login event in the Audit logs were authorized (below)

8   1418168577  2   bob.smithi  91.76.169.010   allowed /login.php

Any recommendations on how to do this?

index=audit_logs [search index=access_logs | dedup src | table src | format src]

Make sure that you have ip field renamed to src in both the sources.

Sub search will produce unique src ips and will be given input to audit logs to find the matches.
