If you have a large data set of IP addresses and have to break them into smaller files in order to upload them into the OnSpot platform, but still need the data combined for audience creation, publishing, and reporting you can add data to an existing IP list.
Add Data to Existing IP Address List
Click the 3 dot action menu to the right of your IP address list in the library, and then select "Add Data." Then, upload your new .csv IP address file.
