the array should look as follows. For each of 250K lines I should push the application name, and then the IP address to the proper application name. Only keeping the unique changes. One application may end up with thousands of members. and there are over 4000 unique application names. I need to create a CSV file of application names by member and the member column will use the ";" as a separator not to interfere with the comma. 

A = (
    application1 => [ "10.10.10.1", "10.10.10.2" ],
    application2 => [ "10.10.10.3", "10.10.10.4", "10.10.10.5" ],
    application3 => [ "10.10.10.1", "10.10.10.3", "10.10.10.6" ],
);
