Search multiple time ranges from lookup

I am looking to search for a given value (an IP in this case) between a specific time range. This is easy to do as a one off, but I have a large number of IP’s I need to search for and would ideally like to have a lookup table, with the IP’s and date ranges and for it to be searched for automatically like the below search.csv lookup, ‘src’,’earliest’,’latest’ ‘1.1.1.1’, 11/27/2015:10:00:00, 11/27/2015:11:00:00 but it doesn’t seem to be working, am I doing something wrong? Is there a batter way to do this ? Thanks!
