Нужно сделать выборку по базе данных в формате CSV

Добрый день!

Задание простое.
Есть база данных диапазонов IP-адресов в формате CSV (размер файла 1.2 GB, Excel его полностью открыть не может) такого вида:

ip_from, ip_to, country_code, country_name, region_name,city_name, provider
"12.16.117.160","12.16.117.191","US","United States","Missouri","Lee's Summit","Encompass Medical Group"
"12.16.117.192","12.16.117.199","US","United States","Missouri","Kansas City","Cogent Inc"
"12.16.117.200","12.16.117.207","US","United States","Kansas","Lawrence","Sanders Software Consulting in"
"12.16.117.208","12.16.117.223","US","United States","Missouri","Riverside","Sears Carpet Air Duct Clean"...
