# Creation steps
1. Create the `ip_address_locations` table
1. Create the `ip_address_locations` table (see `40_ipaddr.sql` file)
2. Obtain the file from http://geolite.maxmind.com/download/geoip/database/GeoLite2-City-CSV.zip
3. Uncompress it and upload the `GeoLite2-City-Blocks-IPv4.csv` file
4. Rename the uploaded table as `latest_ip_address_locations`
