Can I use a lookup table of IP ranges + location names to add a location field to network traffic based on IP range?

I have a lookup table of IP ranges with location names. I'm trying to search network traffic and add a "location" field to the result based on what IP range the src_ip falls under. I do not have access to any of the configuration files and would like to know if I can do this within the search. Example of my lookup table (range_location.csv): range location 50.106.56.0 /21 site_1
